Note Making: 4 Marks 1. The word ‘Note’ means a short record of facts etc. made to help the memory. 2. In Note-Making two things are important: i. Find out the different points in the passage and ii. Note the relationship between these points. 3. Also remember that, in Note Making you need to grasp the main idea which could be the theme of the passage. If an essay or an article contains many paragraphs, you will find that every paragraph contains one important point. 1. Draw a tree diagram that contains the main points and important supporting details from the following text about flowering plants. Flowering plants are of various types. Herbaceous flowering plants grow, set seed and die within one year; biennial plant complete their life cycles in two years; Perennials on the other hand, can live and grow for many years once they have been planted. Plants that flourish and flower during the rainy season are mostly herbaceous annuals such as the Aster, Zinnia, and Sweet pea. Of the herbaceous perennials the most common are members of the Daisy family. The beautifully scented Rose and Jasmine are both Woody and Semi-Woody perennials. There are two other types of plants; bulbous plants and aquatic plants. The former grow from bulbs and tubers planted in the Note-Making

ground; examples of this type are Gladiolus and Tulip. The latter, as their name suggests, grow in water, the most exquisite example being the Lotus or Water Lily. Both bulbous and aquatic plants are usually perennials.

Ans: Flowering Plants 2. Draw a tree diagram showing the division of the plant kingdom. Ans: The vast number of plants surrounding us makes it necessary to classify them in order to carry out a systematic study. The plant kingdom can be divided into two groups. Cryptogams which are non-flowering, non-seed–bearing plants and spermatophyte which are flowering seed-bearing plants. Cryptogams can be further sub-divided into three groups. Thallophyta, in which the root stem and leaf absent, Bryophyta in which false roots are present and Peridophyta, in which true roots, stems and leaves are present. Thallophyta can further be divided into Algae, Fungi, Lichens, Bacteria and Virus. Spermatophyta are of two kinds: Angiosperm Note-Making

in which the seeds are enclosed within the fruit and in gymnosperm seeds are naked. 3. Draw a tree diagram that contains the main points and important supporting details from the text about ‘Fat Facts’.

If edible fats like Ghee, butter and oil are the modern equivalent of sin, how is it that only some cooking oils claim to be good for you? The truth is that all fats are not created equal. All of them are equally fattening. But in terms of cholesterol, some types of fats are healthier for you than others. The worst company to keep is saturated fats. These are oils that harden as soon as the weather turns cool. Saturated fats lurk in foods of animal origin, such as meat, poultry, cheese, ghee, butter, cream, lard and eggs. Some vegetable fats are also in same league- coconut oil, palm oil and vegetable ghee. Unsaturated fats which remain liquid even in cool weather are more heartfriendly. Mono-unsaturated are the healthiest because they lower only the „bad cholesterol. Mono-fats are groundnut, mustard and olive oils. Poly-unsaturated oils are corn, sunflower, safflower, soybean and sesame. These also bring down „bad‟ cholesterol but they end up lowering good cholesterol as well. So monos remain

4 Draw a tree diagram showing factors and their supporting details that influence human personality. Human personality is influenced by a wide variety of factors which often act in conjunction. The two broadest factors that have been found to shape human personality development are the biological factors and the socio-cultural factors. Within the biological factors are included genes, chromosomes, neuro-chemical processes, especially the hormones secreted by various glands. Improper functioning of hormonal glands can bring about a wide variety of physical, psychological and emotional changes in the individuals. Socio-cultural factors also play an important role in the molding of an individual‟s personality. Education, mannerism, values, attitude, beliefs, moral ethics, prejudices and certain specific behavior are to a great extent determined by our family and cultural environment. Teachers an peer group also have a significant impact on our personality. Teachers have the not only to motivate children but also to influence then to model many aspects of their behaviour on personality. Peer group refers to other children of the same age who study with or play with the child.

5. Draw a tree diagram that contains the main points and important supporting details from the following text: Astronomers know that all the galaxies in the universe are moving apart at high speed. Three theories have been put forward to explain this. In 1927 a Belgian astronomer called Georges proposed the Big Bang Theory. He suggested that the universe began as a vast explosion from a central mass of matter. The resulted debris formed the galaxies which are still moving outwards. A variation of this theory states that the Universe is constantly exploding outwards, drawing back together into a mass and exploding again. This continuous cycle is called the Oscillating Universe Theory. In 1948 Fred Hoyle and two other British astronomers proposed a completely different theory called the Steady State theory. According to this, the appearance of the Universe remains the same all the time. As the galaxies move apart, new matter is being created to occupy the empty space. Astronomical Theories

6. Draw a tree diagram that contains the main points and important supporting details from the text. We all read for a variety of reasons. These reasons change with our age, our interests, and the literature we read. Our basic reason for reading is probably pleasure. We read literature mostly because we enjoy it. Reading for pleasure may take various forms. We may read just to pass the time. Or, we may want to escape the four walls that usually surround us. Reading serves as a jet airplane that speeds us away from ourselves into the worlds of other people. We often read for the information and knowledge. We find pleasure in learning about life in the Swiss Alps or on the Mississippi River. We find possible solutions to our problems when we meet people in books whose problems are like our own. Through literature, we sometimes understand situations we could not otherwise understand in real life. We also read simply for the enjoyment we get from the arrangement of the words. We can find pleasure even in nonsense syllable, just as children like the sound of “Ring around the Rosie” although they may not know what the words mean. Reasons for Reading Pleasure

metric tons are spewed out from exhaust pipes of motor vehicles. Of these, the most dangerous are lead and carbon monoxide. A study in 1994 conducted by the center for Research Development, Mumbai, concluded that carbon monoxide emitted by petrol-burning auto engines is picked up more easily than oxygen by the hemoglobin in the blood. It thereby reduces the blood‟s capacity to transport oxygen throughout the body. Moreover, when carbon monoxide enters the lungs it corrodes the respiratory tract, leading to respiratory diseases. Lead is a poisonous substance. Unfortunately children are much more vulnerable to lead poisoning than adults as it retards their growth. Ans: Title: Pollution 1. Levels of pollution A] 2000 m tones of pollutants added everyday B] 1300 m tones spewed out from exhaust pipes of motor vehicles. 2. Major pollutants A] Lead B] Carbon monoxide 3.

Additional Questions for Practice 1.

Read the following passage and draw a tree-diagram that contains the main

points and important supporting details. In what strange dwellings do people live! On the lakes of Kashmir, there are people who live, work and die in boats. These boats are large and heavy and are called houseboats. In Africa, some tribes live in houses in the tops of trees, or even in houses perched on stilts. Far up in the cold north. The Eskimos builds igloos out of ice blocks. They crawl in and out of them through a small opening which is just big enough to let a man through. In the burning deserts the nomadic tribes live in tents which they can quickly take down and put up. And in t he world‟s big cities men live in tall skyscrapers high above the noise of busy streets. 2. Draw a tree-diagram that contains the main points and important supporting details from the extract. In India, the parliament has two houses, viz. the Council of States and the House of People. Besides, the President is an integral part of it. The Council of States possesses 250 members who are elected from the States and Union territories on the basis of population. Among 250 members, there are 238 members who represent states and 12 members who are nominated by the President of India from among the distinguished personalities/ contributors in various fields. The House of the People possesses 552 members who are elected by the people. Among 552 members, there are 530 members from the states, 20 members from Note-Making

Union Territories and 2 members nominated by the president from the Anglo Indian Community. The Council of States and the House of the people are called the Upper house of the Parliament respectively.

3. Draw a tree-diagram that contains the main points and important supporting details from the extract. You probably have some idea as to what Biology is. It is the study of animals and plants. Biology includes all that is known about any living thing, any plant or animal of the past or present. But Biology is more than mere accumulated knowledge of the individual kinds of plants and animals. The known facts about particular kinds of living things are used to discover the great principles and laws that govern all life. Biology sees life as a whole as well as living thing one by one. From this point of view, biology may be defined as the science of life. Biology is important to all mankind because it helps to solve a variety of problems. The knowledge that has enabled us to increase our food supply and to control plant diseases and pests comes from Biology. The improved methods of growing plants and the production of new varieties of plants are possible because of the ever-growing science of living things. Those who raise cattle and poultry to supply our demand for meat, milk and eggs find Biology important in many ways. Life in a city like Mumbai would be rather difficult without the services of Biologists. Milk and water must be kept from spreading diseases. Food must be inspected. Sewage is properly disposed off. Contagious diseases must be kept from spreading. Citizens must be treated so that they will not contact small pox, diphtheria, typhoid, rabies and many other preventable diseases. Every person who lives in a city depends on Biology for continued good health. Dentists, druggists, doctors, nurses, museum workers, zoo keepers all these use the findings of Biology Note-Making

in their everyday work. 4.

Matter is classified under three parts, namely, elements, compounds and mixtures. We are familiar with iron bars, aluminum utensils, copper wires, gold ornaments, oxygen and hydrogen. We try to break up iron or copper particles into very minute. In particles we don‟t get any other substance but that substance only. These substances are called elements. Elements are classified into metals and nonmetals. Gold, silver, iron, copper etc. are examples of metals. Oxygen, Hydrogen, Sulphur and carbon are example of non-metals. In some elements like Antimony and Silicon properties of both metals and non-metals are observed. Water, Common Salts and sugar are examples of compounds. The air we breathe is made of gases. Tea we drink is made up of Water, sugar extract of tea leaves and milk. Wood is composed of cellulose, lignin, gum and resins. These are all mixtures. 5.

Draw a tree diagram that contains the main points and important supporting

details from the text about man’s dependence on plants. Man is dependent upon plants for his very existence on Earth. From plants he secures food, shelter and materials for clothing. Some plants yield drugs of medicinal value, other yield products such as rubber, oils, gums, dyes, cork and turpentine, and still others are used to adorn our homes and gardens. All our fuel is of plant origin, including coal, kerosene and petroleum. The most significant feature of green plants is that they have the unique power of strong energy from sunlight. Therefore, the food of all animal is derived directly or indirectly from plants. Is it any wonder that man has been interested in plants since the dawn of Note-Making

history? Primitive man soon learned that some wild plants would bountifully supply his needs. He collected seeds and planted them and gradually brought the domestication of few plants which were useful to him. Similarly, he took special interest in which have curative properties. Amongst the earlier records of the study

11

of plants are those which are concerned with medical properties. http://senenglish.webs.com/

Plants occur everywhere on or near the surface of our planet. Wherever man has gone, even in the Polar Regions and on the summits of mountains, plants are found. Besides the familiar green trees and herbs there are countless small plants, many of them microscopic which occur in water, deep in the soil and in the air. Many kinds of bacteria live on and within the bodies of human beings, animals and larger plants. Such small plants may be of immense use to human beings, or they may very harmful effects. The thousands of different kinds which make up the vast population of plants fall into different groups the study of which is called the classification of the plant kingdom. 6. Draw a tree diagram that contains the main points and important supporting details from the text about zoology. Zoology is the science that deals with animals. It is an old, old science, almost as old as man himself. Some modern scientists say that man has been living on this planet for about a million years. The science of zoology began with man‟s curiosity about life. Pictures on the walls of rock shelters are show the life of people who lived in the Sahara desert between 8000 and 4000 B.C. like many prehistoric people, these early artists showed an interest in animal life drawing pictures of various birds and mammals which they used to eat. Whatever your work in the world may be, your life will be enriched by knowledge of living things, and this information will also help you in understanding some of the most important problems of our times such as population growth, diseases, the effect of radiation on life and man‟s survival in Note-Making

our space. Everyone is familiar with many of the common animals and knows something about where and how they live, but few people realize how many different kinds of animals there are and how different they are from each other in size, shape,

12

http://senenglish.webs.com/

structure and habits. It is easy to observe larger types, such as cats, birds, frogs, and even some similar ones, such as earthworms and flies; but many members of the animal kingdom are so small that they can be seen only with the aid of the microscope. Then there are forms that live in the soil, in the ocean, and in the air where we do not ordinarily see them. No one knows exactly how many different kinds of animals there are now in existence, but we do know that more than one million have been described by zoologists. Fortunately for us, although they differ from each other they possess characteristics in common and can be arranged in groups. The principal groups are called “phyla” (singular “phylum”). Zoologists do not agree about the number of phyla into which the animal kingdom should be divided, but usually eleven are studied in some detail in a zoology course for beginners. Besides these, there are few groups of animals of more or less uncertain relationships. 7.

Read the following extract and make a note of important points: Hepatitis means inflammation of the liver, which leads to jaundice. The

common causes of hepatitis are viral hepatitis (especially A and C followed by B) and alcoholic hepatitis. In rare cases one encounters hepatitis due to parasites, chemicals, drugs and malignant deposits. Hepatitis A and C are transmitted by contaminated water food whereas. Hepatitis B is transmitted by injections, injuries, surgery and blood transfusion with patients suffering from these diseases. Note-Making

The symptoms of hepatitis differ from virus to virus but generally in the initial stages the patient gets fever without a septic focus i.e. sore throat, cold etc. the fever is associated with body ache, headache and loss of appetite and is moderate to high grade and generally doesn‟t responds.

Read the following extract and make a note of following points: Open University is different from other Universities like University of Puna

or

University of Mumbai. But like all Universities, it also gives degrees like

B.A. and B.Com. Many of us cannot go to colleges and Universities. Many of us are employed and have to work for the whole day. We do not have time to go to colleges. The advantages of Open University are that we can study at home. We do not have to go to colleges. The Open University sends us books. We can study these books and go for examination. Thus, in Open University, there is no teacher. The books are teachers. If we have difficulties, we can go to our study centre. We can also listen to audio cassettes at the study centre. Another advantage of Open University is that we can learn at our own speed, we can learn according to our convenience. We must develop good habits and good studying habits when we study at Open University. 9.

Read the following passage and put the information in tabular form. The original material from which soil has been formed through long ages are

the rocks of the earth‟s crust. There are three kinds of rocks, made in three different ways. Igneous rocks were made when the molten materials of which the earth consisted long ago become cooler and solidified, granite, is one of these. Another kind of rock is sedimentary rock, formed when rivers brought down small pieces of materials with them fell to the bottom of the sea, and this sediment was slowing press and cemented together by another substances into rock. Shale,

Note-Making

Limestone and chalks are sedimentary rocks. This was formed, for instance, when the lava thrown out by volcanoes affected the material over which it flowed. The heat changed the surface underneath and produced different kinds of rocks, of which slate and marble are two examples.
