Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants respire through
A
Root
B
Stem
C
Leaf
D
All the above
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: -Stomata: Plant breathe through tiny openings in leaves known as stomata. Stomata functions by opening and closing for the intake of carbon dioxide as well as releasing oxygen. The oxygen from the air enters the leaf through the stomata and reaches all the cells through diffusion.

Detailed explanation-3: -Every part of a plant such as the leaves, stem, roots and even the deepest-placed cell in any region respires. Respiration in Plants is a process in which plants absorb free oxygen molecules to create water, carbon dioxide, and energy, required for plants.

Detailed explanation-4: -How Does Respiration Occur in Roots? The roots of a plant take up air from the spaces between the soil particles. Root hairs are in contact with the air in the soil particles. Oxygen from the air in soil particles diffuse into root hair and reach all the cells of the root where it is utilised in respiration.

Detailed explanation-5: -Plants take in oxygen and give out carbon dioxide during respiration.
