The phenomenon of uptake of water at the expense of energy by the cell and usually against osmotic gradient is known as:
active absorption
Correct answer is option A
Explanation for correct option:
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.
