Explanation:
Detailed explanation-1: -Consequently, leaves, stems and roots of plants separately exchange gases. 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: -This happens in the following way: By diffusion, oxygen from the air enters a leaf through stomata and reaches all of the cells. The leaf’s cells utilise this oxygen for respiration. Through the same stomata, the carbon dioxide created during the process diffuses out of the leaf into the air.
Detailed explanation-3: -Diffusion is the process by which plant parts like roots, stems, and leaves get the oxygen required for respiration.
