NEET BIOLOGY

Detailed explanation-1: -The oxygen that is produced during photosynthesis is released through the stomata present in the leaf. Transpiration process also occurs through these pores present in the leaves.

Detailed explanation-2: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-3: -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-4: -A stoma is a pore, found in the leaf and stem epidermis that is used for gas exchange. The pore is bordered by a pair of specialised parenchyma cells known as guard cells which are responsible for regulating the size of the opening. The inner wall of the guard cells is thicker than the outer wall.

Detailed explanation-5: -Stomata are cell structures in the epidermis of tree leaves and needles that are involved in the exchange of carbon dioxide and water between plants and the atmosphere. From: Introduction to Forestry and Natural Resources, 2013.
