Question

The absorption of water due to expenditure of energy is called as ____________.

• A. Active absorption
• B. Non-smotic absorption
• C. Passive absorption
• D. All of the above

Answer 1

The correct option is A Active absorption

It is called water absorption 'through roots', rather 'by' roots. It occurs in rapidly transpiring plants during the daytime, because of the opening of stomata and the atmospheric conditions. The force for absorption of water is created at the leaf end i.e. the transpiration pull.
