Match the items given in Column I with those given in Column II: Column I Column II (i) Yeast (a) Earthworm (ii) Diaphragm (b) Gills (iii) Skin (c) Alcohol (iv) Leaves (d) Chest cavity (v) Fish (e) Stomata (vi) Frog (f) Lungs and skin (vii) Insects (g) Tracheae

(i) - (c) Yeast is a single-celled fungus. It converts sugar through fermentation, into carbon dioxide and alcohol. (ii) - (d) A large muscular sheet called diaphragm forms the floor of the chest cavity. Breathing involves the movement of diaphragm and the rib cage. (iii) - (a) Earthworms breathe through their skin. Oxygen and carbon dioxide pass through the earthworm's skin by diffusion. For diffusion to occur, the earthworm's skin must be kept moist. (iv) - (e) Stomata are typically found in plant leaves that controls the rate of gas exchange. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. (v) - (b) There are many organisms that live in water. Gills in fish help them to use oxygen dissolved in water. Gills are projections of the skin. Gills are well supplied with blood vessels for exchange of gases. (vi)-(f) Frogs can stay in the water as well as on land. Although frogs have a pair of lungs like human beings, they can also breathe through their skin, which is moist and slippery. (vii)-(g) Insects have a network of air tubes called tracheae for gas exchange. Oxygen rich air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches every cell of the body. Similarly, carbon dioxide from the cells goes into the tracheal tubes and moves out through spiracles.
