Question

Describe the process of respiration in the following part of a plant:

Root

Short Note

Solution

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.
