The process through which plants leaves, stems and roots consume oxygen and give off carbon dioxide is?
A
absorption
B
translocation
C
respiration
D
photosynthesis
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: -Respiration In Leaves This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.

Detailed explanation-3: -Thus the respiration in roots occurs by diffusion of respiratory gases through the root hairs. b Respiration in stems: The stems of herbaceous plants takes place through stomata. The oxygen from the air diffuses into the stem of a herbaceous plant through stomata and reaches all the cells for respiration.
