Expert Answer
- Stomata are the minute openings present on the surface of leaves. They are responsible for the gaseous exchange in plants. During daytime, carbon dioxide enters through the stomata and used up for photosynthesis. Oxygen produced is given out through stomata. At night, it is vice a versa, oxygen is taken in while carbon dioxide is given out through stomata. During transpiration, the excess amount of water is also expelled out through stomata in the form of water vapour.
- Snakes respire through the normal contraction and relaxation of muscles present between the ribs. However, they lack a diaphragm.
