Answer –
\n<\/strong>(i) The blood from the heart is transported to all parts of the body by the\u00a0arteries<\/strong><\/span>.
\n(ii) Haemoglobin is present in\u00a0red blood<\/strong><\/span>\u00a0cells.
\n(iii) Arteries and veins are joined by a network of\u00a0capillaries<\/strong><\/span>.
\n(iv) The rhythmic expansion and contraction of the heart is called\u00a0heartbeat<\/strong><\/span>.
\n(v) The main excretory product in human beings is\u00a0urea<\/strong><\/span>.
\n(vi) Sweat contains water and\u00a0salts<\/strong><\/span>.

3. Choose the correct option:
\n<\/strong>(a) In plants, water is transported through
\n<\/strong>(i) xylem
\n(ii) phloem
\n(iii) stomata
\n(iv) root hair<\/span><\/p>\n

Answer –\u00a0<\/strong>(i) xylem<\/span><\/p>\n

(b) Water absorption through roots can be increased by keeping the plants
\n<\/strong>(i) in the shade
\n(ii) in dim light
\n(iii) under the fan
\n(iv) covered with a polythene bag<\/span><\/p>\n

Answer – <\/strong>(iii) under the fan<\/span><\/p>\n

4. Why is transport of materials necessary in a plant or in an animal? Explain.<\/strong><\/span><\/p>\n

Answer –\u00a0 <\/strong>The cells of different organs of plants and animals need various necessary substances to carry out many metabolic activities and different type of waste products are created during these metabolic activities. So, transport of materials is necessary to supply the required substances and to remove the waste products.<\/span><\/p>\n

5. What will happen if there are no platelets in the blood?<\/strong><\/span><\/p>\n

Answer –\u00a0 <\/strong>If there are no platelets in the blood, then the blood would not be able to clot. A clot is formed because of platelets. They release blood clotting chemicals at the site of injury. These chemicals form a clot and prevent further bleeding.<\/span><\/p>\n

6. What are stomata? Give two functions of stomata.<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Stomata are tiny pores present on the surface of a leaf.
\nFunctions of stomata:<\/strong>
\n(a) Stomata help in the exchange of gases.
\n(b) Evaporation of water from the leaf surface occurs through stomata.<\/span><\/p>\n

7. Does transpiration serve any useful function in the plants? Explain.<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Transpiration serves a very important function in plants. It is the loss of water through stomata. Transpiration creates the transpiration pull, which is responsible for the rise of water to great heights in tall plants and other trees.<\/span><\/p>\n

8. What are the components of blood?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>There are four components of blood:<\/span><\/p>\n
