    NCERT Class 6 English Unit 9 – What Happened To The Reptiles

    Exercise Questions (Page 42)

    Question 1:

    In what way is Pambupatti different from any other village?NCERT Class 6 English Unit 9 – What Happened To The Reptiles

    Answer:

    People in Pambupatti lived peacefully as they did not fight or get involved in communal riots in the name of religion or language. This proved that Pambupatti was not like any other village, but different from them.

    Question 2:

    Why is Prem determined not to return to his village?

    Answer:

    Prem was determined not to return to his village because communal riots of hate and violence were happening in his village. He and other villagers felt that it was unsafe for them to reside in the village where houses were being burnt in fire and people were killing each other and getting involved in communal violence.

    Question 3:

    Why did Makara dislike tortoises, snakes and lizards? Write a line about each.

    Answer:

    Makara disliked tortoises because they were slow and stupid, who carried their houses on their backs.

    Makara disliked snakes because they were slimy, made funny noises and were poisonous in nature.

    Makara disliked lizards because they had the strangest habits such as changing colour which made them unreliable.

    Question 4:

    What went wrong when the tortoises, snakes and lizards left the forest?

    Answer:

    When the tortoises, snakes and lizards left the forest, it went through a tough phase. The forest filled with a rotting smell of fruits and animals due to the absence of the tortoises. Once the snakes left, the forest was taken over by the rats as there was no one to eat them. Finally, the nasty insects grew bigger and multiplied in millions due to the absence of the lizards.

    Question 5:

    Why do you think Prem wants to tell the story of the reptiles to the people of his village?

    Answer:

    Prem wanted to tell the story of the reptiles to the people of his village because he understood that they had unnecessarily involved themselves in communal violence. He wanted the people of his village to live peacefully and maintain law and order. The story of the reptiles underlined the significance of living together in peace and harmony like Pambupatti.

    Question 6:

    Do you agree that it is difficult not to go along with someone who is very strong and powerful? Express your views frankly and clearly.

    Answer:

    On a general note, common people are peace-loving, weak and submissive in nature. Most of them do have fear of the strong and powerful people due to their tyranny and unjust exercise of authority. It is a facet of human nature of ordinary people to adhere to the interests of the strong lot in order to maintain their own safety and security. But if such common people raise their bar by standing up against the bullies and start voicing their opinion against the tyrants, they are likely to suppress oppression and maintain peace and harmony in the society.

    Question 7:

    If you were a baby crocodile, would you tell Makara that he was wrong? What would you say to convince him?

    Answer:

    Being a baby crocodile, I would definitely explain to Makara the consequences the forest might face if the other reptiles left it. Besides, I would also mention that every living organism has the right to live on its own wherever it wants. It is imperative for the strong people to protect the ordinary masses and not take undue advantage of their weaknesses. Therefore, every living being is interdependent upon each other and has a vital role to play to maintain the ecological balance in the beautiful environment of the Earth.

    A STRANGE WRESTLING MATCH

    NCERT Solutions Class 6 English – Chapter 10

    A Strange Wrestling Match

    Questions

    Question 1: What was Vijay Singh’s weakness? Which awkward situation did it push him into?

    Answer: Vijay Singh’s weakness was that he was fond of boasting. He boasted that he wished that he met a ghost and taught him a lesson. This pushed him to an awkward situation where he was suggested to go to the Haunted Desert where he could find ghosts.

    Question 2. Was the old woman’s gift to Vijay Singh eccentric? Why?

    Answer: The old woman gifted a lump of salt and an egg to Vijay Singh. Yes, the gift was eccentric because Vijay Singh could not understand what the purpose of such a gift was on a desert.

    Question 3Why did Vijay Singh ask the ghost disguised as Natwar to come closer?

    Answer: Vijay Singh asked the ghost disguised as Natwar to come closer so that he could size up his enemy like all other good wrestlers.

    Question 4What made the ghost speechless? Why?

    Answer: Vijay Singh pretended to be brave. He looked at Natwar’s face and said that he was a plain, lying ghost. This made the ghost speechless because people used to get afraid when they saw him but here, Vijay Singh was brave and confident.

    Question 5Why did Vijay Singh say “Appearances can be deceptive”?

    Answer: Vijay Singh said that “Appearances can be deceptive” because he wanted to insult the ghost. He wanted to show the ghost that he was very confident and strong enough to make the ghost lose.

    Questions

    Question 1: How did Vijay Singh use the egg? How did he use the lump of salt?

    Answer: Vijay Singh handed over a rock to the ghost and asked him to squeeze it. He told the ghost that the rock was full of fluid. The ghost was unable to squeeze the rock. Then, Vijay Singh insulted the ghost and carefully took the egg in his hand and took the rock from the ghost. He squeezed the egg, the yellow fluid dripped down and made the ghost think that he actually squeezed the rock.

    Vijay Singh then challenged the ghost to crush another rock. This time, he said that it was nothing but salt. The ghost could not crush the rock. Then Vijay Singh took the lump of salt from his pocket and the rock from the ghost in his hand. He crumbled the lump of salt and let the rock drop into the darkness. Thus, Vijay Singh showed that he was way more powerful than the ghost.

    Question 2. Why did Vijay Singh conclude that the ghost would not be a worthy opponent to him? Was he fair in his judgement?

    Answer: Vijay Singh concluded that the ghost would not be a worthy opponent to him as he could not perform any of the challenges that Vijay Singh threw on him- neither could he crush the rock full of fluid nor he could crumble the rock made of salt.

    No, he was not fair in his judgement because he used unfair tricks to prove that he was more powerful than the ghost.

    Question 3Why did Vijay Singh ask the ghost to accompany him to town next day?

    Answer: Vijay Singh asked the ghost to accompany him to town the next day so that he could boast that he claimed victory even in a fight with a ghost. He wanted the ghost to accompany him as his prisoner.

    Question 4What made the ghost believe Vijay Singh was dead?

    Answer: There was no sound or groan in response to the ghost’s beating on the bolster, which he thought to be Vijay Singh. This made the ghost believe that Vijay Singh was dead.

    Question 5Vijay Singh complained of insects in the cave. What was he referring to, and why?

    Answer: Thinking that Vijay Singh was sleeping on the bed, the ghost had beaten him seven times with his stout club.

    Vijay Singh complained that some insect flapped him with its wings seven times. He did so to prove that he was so powerful that those beatings with the stout club were as powerless as an insect’s flap.

    Question 6Was it really a ghost who Vijay Singh befooled? Who do you think it was?

    Answer: No, it was not really a ghost who Vijay Singh befooled. I think he was a fraudulent human who used to trick people into thinking that he was a ghost. Taking advantage of their fear, he would loot them of their possessions.

    NCERT Solution – Class 11 Biology :Biological Classification :

    1. Discuss how classification systems have undergone several changes over a period of time?

    Answer

    The classification systems have undergone several changes with time. The first attempt of classification was made by Aristotle. He classified plants as herbs, shrubs, and trees. Animals, on the other hand, were classified on the basis of presence or absence of red blood cells. This system of classification failed to classify all the known organisms.Therefore, Linnaeus gave a two kingdom system of classification. It consists of kingdom Plantae and kingdom Animalia. However, this system did not differentiate between unicellular and multicellular organisms and between eukaryotes and prokaryotes. Therefore, there were large numbers of organisms that could not be classified under the two kingdoms.To solve these problems, a five kingdom system of classification was proposed by R.H Whittaker in 1969. On the basis of characteristics, such as cell structure, mode of nutrition, presence of cell wall, etc., five kingdoms, Monera, Protista, Fungi, Plantae, and Animalia were formed.

    2. State two economically important uses of:
    (a) Heterotrophic bacteria
    (b) Archaebacteria

    Answer

    Two economically important uses of Heterotrophic bacteria are:
    → They help in the production of curd from milk.
    → Many antibiotics are obtained from some species of bacteria.

    Two economically important uses of Archaebacteria are:
    → Methane gas is produced from the dung of ruminants by the methanogens.
    → Methanogens are also involved in the formation of biogas and sewage treatment.

    3. What is the nature of cell-walls in diatoms?

    Answer

    The cell walls in diatoms are embedded with silica, which makes them indestructible. They form two thin overlapping shells which fit together as in a soap box. Thus diatoms have left behind large amounts of cell wall deposits in their habitat.

    4. Find out what do the terms ‘algal bloom’ and ‘red-tides’ signify.

    Answer

    Algal bloom refers to an increase in the population of algae or blue-green algae in water, resulting in discoloration of the water body.

    Red tides are caused by red dinoflagellates that multiply rapidly. Due to their large numbers, the sea appears red in colour. Toxins released by them can kill other marine species.

    5. How are viroids different from viruses?

    Answer

    Viroids are free RNAs without the protein coat, while virus have a protein coat encapsulating the RNA.

    6. Describe briefly the four major groups of Protozoa.

    Answer

    The four major groups of Protozoa are:

    • Amoeboid protozoans: These organisms live in fresh water, sea water or moist soil. They move and capture their prey by putting out pseudopodia (false feet) as in Amoeba. Marine forms have silica shells on their surface. Some of them such as Entamoeba are parasites.

    • Flagellated protozoans: The members of this group are either free-living or parasitic. They have flagella. The parasitic forms cause diaseases such as sleeping sickness. Example: Trypanosoma.

    • Ciliated protozoa or ciliates: They are aquatic individuals that form a large group of protozoa. Their characteristic features are the presence of numerous cilia on the entire body surface and the presence of two types of nuclei. All the cilia beat in the same direction to move the water laden food inside a cavity called gullet. Example: Paramoecium, Vorticella,etc.

    • Sporozoans: They include disease causing endoparasites and other pathogens. They are uninucleate and their body is covered by a pellicle. They do not possess cilia or flagella. They include the malaria causing parasite Plasmodium.

    7. Plants are autotrophic. Can you think of some plants that are partially heterotrophic?

    Answer

    Some insectivorous plants, like bladderwort and venus fly trap are partially heterotrophic.

    8. What do the terms phycobiont and mycobiont signify?

    Answer

    Lichens are good examples of symbiotic life of algae and fungi. Phycobiont is the name of the part composed of algae and Mycobiont is the name of the part composed of fungi. Fungi provide minerals and support to the alage, while algae provide nutrition to the fungi.9. Give a comparative account of the classes of Kingdom Fungi under the following:
    (i) Mode of nutrition
    (ii) Mode of reproduction

    Answer

    → Phycomycetes- This group of fungi includes members such as Rhizopus, Albugo, etc.
    • Mode of nutrition: They are obligate parasites on plants or are found on decaying matter such as wood.
    • Mode of reproduction: Asexual reproduction takes place through motile zoospores or non-motile aplanospores that are produced endogenously in sporangium.
    Sexual reproduction may be of isogamous, anisogamous, or oogamous type. It results in the formation of thick-walled zygospore.

    → Ascomycetes- This group of fungi includes members such as Penicillium, Aspergillus,Claviceps, and Neurospora.
    • Mode of nutrition: They are sporophytic, decomposers, parasitic or coprophilous.
    • Mode of reproduction: Asexual reproduction occurs through asexual spores produced exogenously, such as conidia produced on conidiophores.
    Sexual reproduction takes place through ascospores produced endogenously in sac – like asci and arranged inside ascocarps.

    → Basidiomycetes- This group of fungi includes members such as Ustilago,Agaricus and Puccinia.
    • Mode of nutrition: They grow as decomposers in soil or on logs and tree stumps. They also occur as parasites in plants causing diseases such as rusts and smuts.
    • Mode of reproduction: Asexual reproduction takes place commonly through fragmentation. Asexual spores are absent.
    Sex organs are absent but sexual reproduction takes place through plasmogamy. It involves fusion of two different strains of hyphae. The resulting dikaryon gives rise to a basidium. Four basidiospores are produced inside a basidium.

    → Deuteromycetes – This group of fungi includes members such as Alternaria, Trichoderma, and Colletotrichum.
    • Mode of nutritionSome members are saprophytes while others are parasites. However, a large number act as decomposers of leaf litter.
    • Mode of reproduction: Asexual reproduction is the only way of reproduction in deuteromycetes. It occurs through asexual spores called conidia.
    Sexual reproduction is absent in deuteromycetes.

    10. What are the characteristic features of Euglenoids?

    Answer

    Characterisitic Features of Euglenoids:
    → Fresh water organisms found in stagnant water.
    → Instead of cell wall they have a protein rich layer called pellicle whick makes their body flexible.
    → They are autotrophs in the presence of sunlight and heterotrophs in the absence of sunlight.
    → A small light sensitive eye spot is present.

    11. Give a brief account of viruses with respect to their structure and nature of genetic material. Also name four common viral diseases.

    Answer

    Viruses have a protein capsule and genetic materials inside the capsule. These genetic material become active once they are inside the nucleus of a host cell. They start replicating themselves and in turn spreading the disease.
    Generally viruses that infect plants have single stranded RNA. Viruses infecting animals have double stranded RNA or DNA. Viruses which infect bacteria have double stranded DNA.A.I.D.S, small pox, mumps, and influenza are some common examples of viral diseases.

    12. Organise a discussion in your class on the topic- Are viruses living or non-living?

    Answer

    Viruses are microscopic organisms that have characteristics of both living and non-living. A virus consists of a strand of DNA or RNA covered by a protein coat. This presence of nucleic acid (DNA or RNA) suggests that viruses are alive. In addition, they can also respond to their environment (inside the host cell) in a limited manner.
    However, some other characters, such as their inability to reproduce without using the host cell machinery and their a cellular nature, indicate that viruses are non-living. Therefore, classifying viruses has remained a mystery for modern systematics.

    1.5Summary

    NCERT Solution – Class 11 Biology The Living World :

    1. Why are living organisms classified?

    Answer

    The diversity of living beings makes it a challenge to systematically study them. Classification is a helpful tool to categorize them based on certain common characteristics. This enables scientists to study them in a more systematic way. The study of living beings is essential for the benefit of humankind. Discovery of new medicines, and better yielding crop varieties can be made possible only by systematic study of living beings. Moreover, environmental protection also makes it necessary for us to study the living beings in a systematic way.

    2. Why are the classification systems changing every now and then?

    Answer

    Millions of plants, animals, and microorganisms found on earth, have been identified by the scientists while many new species are still being discovered around the world. Therefore, to classify these newly discovered species, with new characters, new systems of classification have to be devised every now and then. This creates the requirement to change the existing systems of classification.

    3. What different criteria would you choose to classify people that you meet often?

    Answer

    In our day to day life we categorize people based on the basis of level of education, profession, hobbies, native place, sex etc.

    4. What do we learn from identification of individuals and populations?

    Answer

    In a diverse country like India we can learn from identification of individuals and populations about the native place, mother tongue, costumes, food habit, religion, caste, etc.

    5. Given below is the scientific name of Mango. Identify the correctly written name.
    Mangifera Indica
    Mangifera indica

    Answer

    In binomial system of nomenclature, the generic name of a species always starts with a capital letter whereas the specific name starts with a small letter. Therefore, the correct scientific name of Mango is Mangifera indica.

    6. Define a taxon. Give some examples of taxa at different hierarchical levels.

    Answer

    A particular level of hierarchy in the classification of living beings is called a taxon. For example, the basic level of classification is species, followed by genus, family, order, class, phylum or division, in ascending order.

    7. Can you identify the correct sequence of taxonomical categories?
    (a) Species → Order → Phylum → Kingdom
    (b) Genus → Species → Order → Kingdom
    (c) Species → Genus → Order → Phylum

    Answer

    Both (a) and (c) represent correct sequences of taxonomic categories as the correct hierarchical arrangement of taxonomic categories in ascending order is
    Species → Genus → Family → Order → Class → Phylum → Kingdom
    In sequence (b), species should have been followed by genus. Therefore, it does not represent the correct sequence.

    8. Try to collect all the currently accepted meanings for the word species. Discuss with your teacher the meaning of species in case of higher plants and animals on one hand and bacteria on the other hand.

    Answer

    In biological terms, species is the basic unit of taxonomy. It can be defined as a group of similar organisms capable of interbreeding freely among themselves under natural conditions to produce fertile off springs.
    Therefore, a group of similar individuals that are reproductively isolated from other group of individuals form a species.
    Species can also be defined as group of individuals that share the same gene pool.

    9. Define and understand the following terms:

    Answer

    (i) Phylum: A group of closely related classes is called phylum. For example: pisces, amphibia, reptilia, aves and mammalia belong to the Phylum Chordata.(ii) Class: The group of closely related orders is called class. For example: orders Primata and Carnivora belong to the class Mammalia.(iii) Family: A group of closely related genera is called a family. For example: family hominidae contains Apes, Monkeys and Man. In plants, families are categorized on the basis of vegetative and reproductive features.(iv) Order: A group of closely related families is called order. For example: order carnivora, includes many families.(v) Genus: A group of closely related species is called genus. For example: genus Solanum, includes many species such as nigrum, melongena, tuberosum, etc.

    10. How is a key helpful in the identification and classification of an organism?

    Answer

    Key is taxonomical aid used for identification of plants and animals based on the similarities and dissimilarities. Selection of one character leads to rejection of another character while identifying a particular species or genera or family and so on. For example presence or absence of hair on body can give a clue if an animal belongs to mammalian or not.

    11. Illustrate the taxonomical hierarchy with suitable examples of a plant and an animal.

    AnswerClassification of a plant

    As an example, let us classify MangoPhylum: Angiosperm
    Class: Dicotyledons
    Order: Sapindales
    Family: Anacardiaceae
    Genus: Mangifera
    Species: Mangifera indicaClassification of a animal

    As an example, let us classify Humans
    Phylum: Chordata
    Class: Mammalia
    Order: Primata
    Family: Hominidae
    Genus: Homo
    Species: Homo sapiens

    what is notes ?

    This guide is about why we make notes, how to make practical notes from speeches and readings, and explains the different ways of making notes.

    Making notes is not just about writing down everything you hear or read. It is a process of reviewing, connecting and combining ideas from your lectures or reading.

    Taking notes helps you to:

    stay active and engage between your lectures, reading and review
    understand what you are reading and clarify your thinking
    select and get key ideas
    remember the story
    organize your ideas and make connections
    planning and constructing written assignments
    review and update before the tests.
    You can also see our tutorial on how to make notes, which explores the various steps you can take to make notes. You will learn different options for making notes in different situations and explore the benefits and features of each method.

    why notes is important for us?

    The importance of note-taking skills for the learner

    Students may have different ways of taking notes, but they are always encouraged. With this practice, one is able to develop the ability to summarize and comprehend information. Research shows that students who find their studies interesting are more likely to make detailed notes.

    Benefits of note writing

    Making notes forces you to translate everything so that you can read it in your own words so that you can understand things better. There are times when students read the whole page in vain without understanding a single word, but if you write notes, then your brain will try to extract the meaning from every single sentence that benefits the readers. Reading notes track all the information they have read. It serves as a ready-to-pass transfer during the pre-test period.

    Taking notes while reading not only saves the student’s energy and time during the exam, but also an easy way to remember things in less time. Study notes not only help students to fill in the blanks, but they can quickly write on the test when they arrive prepared by reading their reading notes. Listed below are some of the benefits of reading notes.

    Improve memory

    Writing notes for reading on paper improves memory, allows students to read more when they read and reduces the chances of forgetting.

    Reading notes increase attention

    Practicing note-taking study should increase students’ attention to detail and focus. Students who focus on the many opportunities to do better in the exams.

    High reason for taking notes: It encourages reading

    Making notes for study stimulates that part of the brain that stimulates learning. Like all muscles in the body, the brain can be trained to read easily to absorb new information quickly.

    You use your brain a lot when you prepare reading notes

    When writing notes for reading while listening, you often make notes by summarizing, organizing and storing only the most important information.

    Increase attention to time

    In terms of reading, learning notes also encourage retention. While learning is an important part of teaching, retention is the ultimate goal needed. Making notes for study improves good memory and the ability to store information because the mind becomes an active object in study. Not only do students understand things better while writing in their own words and handwriting but they also keep it longer.

    Arrange reading materials

    Making notes for inactive study increases the chances of students becoming more organized. Being organized allows students to prioritize tasks and complete tasks on time.

    There are many benefits to study notes, but getting used to taking notes is a necessary skill that students should practice within themselves.

    Separate key points in the supporting content:

    When we are in the upper echelons, the importance of the lessons seems endless. There seems to be no limit to how much one can learn. When a person takes proper notes in class, he will be able to identify important points and separate them easily. This helps save time and speeds up the learning process.

    Teachers suggested a number of textbooks for success during the exams. But is it possible to review all books at the last minute of testing? No, it is not. Here are some practical tips for making notes that help the reader. You know, some of the most successful readers summarize all the books in the form of short notes in such a way that when we read those notes at the last minute we can remember and memorize the whole book.

    Separate the supporting information and help identify it where needed:

    Sometimes we need to find examples of a particular process, or we just need an explanation of one thing and not another. In such cases, the notes are very helpful. Those who take notes effectively have the habit of sorting out the details. One can easily identify and distinguish examples, diagrams, descriptions, and more. This helps to save time and effort. One can easily remember that part only in the notes he needs.

    Notes can be taken anywhere and help over time:

    The best thing about taking notes is that they can be taken anywhere. It can be taken while attending lectures, doing lab work, participating in any teaching or class activity, reading a book, etc. The purpose of notification is to make the learning process easier and faster. Notes can be taken anywhere. Suppose, for example, that you do not have the opportunity to attend class, you can take notes later in life while participating in other activities related to class. This helps to keep track of what was taught.

    Download the form by memorizing the form:

    This is a great advantage of note-taking. We’ve talked about it before. How can we review all the ideas we have received throughout the year on the last day? The books are very large and cannot be read a day or two before the exams, but the notes can be read in two days because it reduces all the information collected in the book / talk into manageable size.

    It speeds up the review process:

    When a person makes notes of all the suffering, he remembers a large part of it. It requires a quick review to remember everything we read. The notes make this process easier to remember. One can easily review specific notes in a day or two. This helps a person to remember everything he has learned and learned throughout the year. Once they have received the suggestion, the students quickly remember all the details. The notes are just those tips. This really speeds up the review and recall process.
