Vedclass · Answer

(D) The absorption of water by roots is influenced by several environmental and soil-related factors. $1$. Soil temperature: Low temperatures decrease the permeability of root membranes and increase the viscosity of water,thereby reducing absorption. $2$. Soil aeration: Adequate oxygen is required for the metabolic activities of root cells,which facilitate active water absorption. $3$. Relative Humidity $(RH)$ of the atmosphere: High humidity reduces the rate of transpiration,which indirectly affects the rate of water absorption from the soil. $4$. Amount of soil water: The availability of water in the soil is the primary determinant for absorption. Therefore,all the listed factors affect the process of water absorption by roots.
