Solution

The correct option is A

active absorption


Correct answer is option A

Explanation for correct option:

  1. When water absorption is against the concentration gradient that is from low solvent concentration to the high solvent concentration.
  2. Then the energy is required to carry out that process.
  3. Hence, it is an active process of absorption.

Explanation for incorrect option:

Option B

Passive absorption is a process in which water absorption is towards the concentration gradient that is from higher solvent concentration to lower solvent gradient.

Option C

Osmosis is the movement of solvent particles from higher water potential to lower water potential through a semi-permeable membrane.

Option D

Diffusion is a process in which the flow of molecules takes place along the concentration gradient that is from a region of higher concentration to lower concentration.

Final answer: The phenomenon of uptake of water at the expense of energy by the cell and usually against an osmotic gradient is known as active absorption.
