If the amount of an ion absorbed by a root hair cell at `0^(@) C` is `5` gm and at `20^(@)C` is `20` gm. The amount of this ion absorbed actively should be

A

25 gm

B

20 gm

C

15 gm

D

5 gm

Text Solution

Verified by Experts

At `0^(@)C`, 5 gm ions are absorbed and at `20^(@)C`, 20 gm ions are absorbed
Energy is increased from`0^(@)C` to `20^(@)C`, then the increase in ion absorption amount `= 20-5 = 15` gm.
