GENERAL HISTOLOGY

Detailed explanation-1: -The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. It also allows the oxygen produced in photosynthesis to leave the leaf easily. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata.

Detailed explanation-2: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata.

Detailed explanation-3: -Carbon dioxide enters the leaves through tiny pores present on the surface of the leaves called stomata. Note: Photosynthesis occurs during the day time. Thu stomata are open mostly throughout the day for supplying the carbon dioxide to the plants. Respiration occurs throughout day and night.

Detailed explanation-4: -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-5: -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.
