NEET BIOLOGY

Detailed explanation-1: -The loss of excess water by diffusion through the stomata of leaves of a plant into the atmosphere is called transpiration. It pulls water up from the roots to different parts of the plant. It also has a cooling effect on the plant.

Detailed explanation-2: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.

Detailed explanation-3: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.

Detailed explanation-4: -Although the surface of a leaf may look smooth, it is lined with tiny openings called stomata. When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them.

Detailed explanation-5: -The correct option is A True. During photosynthesis, Carbon dioxide(CO2) gas is taken in through stomata from the atmosphere. Oxygen(O2) gas is released through stomata into the atmosphere as a by-product.
