Respiration in Roots:

Air occurs in soil interspaces. Root hairs of the roots are in direct contact with them.
Oxygen of the soil air diffuses through root hair and reaches all internal cells of the root for respiration.
Carbon dioxide produced by root cells diffuses in the opposite direction.
In water-logged conditions, soil air becomes deficient. In the absence of oxygen, metabolic activity of the root declines and the plant may wither

The roots of a plant take up air from the spaces between the soil particles. Root hairs are in contact with the air in the soil particles. Oxygen from the air in soil particles diffuse into root hair and reach all the cells of the root where it is utilised in respiration.
