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

The correct Answer is:
C
The rate of absorption of salts and minerals is directly proportional to temperature.
At `0^(@)C` the root hair cell absorbs ion is 5g
At `20^(@)C` the root hair absorb 20 g
Amount of ion absorbed actively is 20g- 5g =15g.
