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

There is a pair of bean-shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unused proteins in the liver is brought into organ P through blood by an artery R. The numerous tiny filters S present in organ P clean the dirty blood by removing the waste product Q. The clean blood goes into circulation through a vein T. The waste substance Q, other waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag-like structure V through two tubes W. This liquid is then thrown out of the body through a tube X.
