How root occur their respiration

1.	How root occur their respiration
Answer» The epidermis cells of new roots give arise to hair like projection called root hairs through which the exchange of gases take place Respiration in Roots:\tAir occurs in soil interspaces. Root hairs of the roots are in direct contact with them.\tOxygen of the soil air diffuses through root hair and reaches all internal cells of the root for respiration.\tCarbon dioxide produced by root cells diffuses in the opposite direction.\tIn 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.
