Root

उत्तर
The respiration in roots takes place by the diffusion of respiratory gases through the root hair. The root hair take the oxygen required for respiration from the air present in-between the soil particles, by the process of diffusion. The oxygen reaches all the other cells of the root for respiration. During respiration, the carbon dioxide gas produced in the cells of the root moves out through the same root hair by the process of diffusion.
