Vedclass · Answer

(C) At $0^o C$,the absorption of ions is primarily passive because metabolic activity is minimal. Thus,$5 \ gm$ represents passive absorption.At $20^o C$,the total absorption is $20 \ gm$,which includes both passive and active transport.Active absorption is the process that requires metabolic energy,which increases with temperature.Therefore,the amount of ion absorbed actively = (Total absorption at $20^o C$) - (Passive absorption at $0^o C$).Active absorption = $20 \ gm - 5 \ gm = 15 \ gm$.

If the amount of an ion absorbed by a root hair cell at $0^o C$ is $5 \ gm$ and at $20^o C$ is $20 \ gm$,then the amount of this ion absorbed actively should be (in $gm$)
