Difference between passive and active absorption of water

It takes place due to activity of upper of the plant such as shoot and leaves.

The water is absorbed due to the action transpiration in aerial parts.

Does not involve the expenditure o energy.

Occurs along a osmotic potential gradient.

The movement of water is through apoplast of root.

Active absorption

i) The active absorption of water takes i) place due to the activity of root and root hairs.

ii) The absorption of water occurs by ii) osmotic and non osmotic process.

iii) Involves the expenditures of metabolic iii) energy

iv) Occurs either along or against an

v) In the movement of water, living parts v) of protoplast (symplast) is invo loved.
