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 $gm$)

Why does active transport occur in roots?

The chief sinks for the mineral elements in plants are:

Unlike water,all minerals cannot be passively absorbed by the root because the concentration of minerals in the soil is usually ....... than the concentration of minerals in the root.

The absorption of mineral nutrients always occurs through active transport because . . . .

$A$: Influx of ions into the inner space of cells is an active process.
$R$: Ions are available for free exchange in the free space.
