Vedclass · Answer

(C) Active absorption of water is an energy-dependent process that requires metabolic energy in the form of $ATP$. This process is mediated by the metabolic activity of root cells,specifically the root hairs. Since metabolic activities like respiration are enzyme-controlled,they are highly sensitive to temperature. The optimal temperature range for most metabolic processes in plants,including active water absorption,is between $20^{\circ}C$ and $35^{\circ}C$. Temperatures below or above this range significantly reduce the rate of respiration and,consequently,the rate of active water absorption.

The suitable temperature range for the active absorption of water by roots is:
