If The Amount Of An Ion Absorbed By A Root Biology Question

If the amount of an ion absorbed by a root hair cell at 0⁰ C is 5 gm and at 20⁰C is 20 gm.The amount of this ion absorbed actively should be


(a) 25 gm
(b) 20 gm
(c) 15 gm
(d) 5 gm

Correct Answer:

15 gm


At 0⁰C, 5 gm ions are absorbed and at 20⁰C, 20gm ions are absorbed.
Energy is increased from 0⁰C to 20⁰C, then the increase in ion absorption amount = 20 – 5 = 15 gm.
