Answer 1

Answer:

Roots of the plant take oxygen from the air that is present in-between the particles of soil. ... It is through root hairs that only carbon dioxide gets diffused into them and is expelled from the roots of a plant. Thus, respiration in roots of the plant occurs by diffusion of oxygen and carbon dioxide through root hairs.
