DENDROLOGY

Detailed explanation-1: -Leaves possess stomata – tiny pores, for gaseous exchange. The oxygen consumed via stomata is used up by cells in the leaves to disintegrate glucose into water and carbon dioxide.

Detailed explanation-2: -Leaves. 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 (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

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: -Plants respire through stomata. Stomata are the small openings (pores) present on the leaves, stems, and other organs of a plant. The small opening of the stomata is guarded by two guard cells that help in opening and closing stomata for gaseous exchange with the atmosphere.

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.
