Match the following: - Column A Column B 1. Stomata (a) Parasite nutrition 2. Iodine solution (b) Green pigment in the leaf 3. Oxygen liberated (c) Tiny pores in the leaf 4. Chlorophyll (d) Turns starch blue-black 5. Amarbel (e) During photosynthesis

(1) - c Stomata help plants to obtain carbon dioxide gas for the process of photosynthesis. They also help in transpiration. Stomata are tiny pores present on the surface of the leaves. (2) - d Iodine solution is used to test the presence of starch in the leaves. Starch is made up of multiple units of glucose. Iodine solution turns blue-black on reacting with starch. (3) - e Living organisms utilise oxygen for the process of respiration. It is produced by the plants during the process of photosynthesis. (4) - b Chlorophyll captures sunlight during the process of photosynthesis. It is a green coloured pigment present in the chloroplast of the plant cells. (5) - a Amarbel grows on big trees and absorbs food and water from them. It shows a parasitic mode of nutrition. Column A Column B 1. Stomata (c) Tiny pores in the leaf 2. Iodine solution (d) Turns starch blue-black 3. Oxygen liberated (e) Photosynthesis 4. Chlorophyll (b) Green pigment in the leaf 5. Amarbel (a) parasite nutrition
