Question

Select the incorrect statement regarding imbibition:

• A. Water is absorbed by germinating seeds through imbibition.
• B. The liquid which is imbibed is called imbibate.
• C. Imbibition is the phenomenon of adsorption of water or any other liquid without forming a solution.
• D. There occurs a decrease in the volume of imbibant during imbibition.

Answer 1

The correct option is D

There occurs a decrease in the volume of imbibant during imbibition.

The correct option is D.

Explanation of the correct option:

1. Imbibition is a process in which water is absorbed by particles of solid substances without forming a solution.
2. The substance that adsorbs water is called imbibant and the liquid which is adsorbed is called imbibate.
3. In imbibition, the water movement takes place along the concentration gradient.
4. As the imbibant takes in water by adsorption, hence the volume of imbibant increases during imbibition.

Explanation of the incorrect option:

Option A:

1. The germinating seeds absorb water by germination.
2. In the absence of imbibition, seedlings would not be able to emerge from the soil.

Option B:

The solid particles that absorb water are called imbibants whereas the liquid that is absorbed is called imbibate.

Option C:

It is a process in which water is absorbed by particles of solid substances without forming a solution.

Final answer: The incorrect statement regarding imbibition is there occurs a decrease in the volume of imbibant during imbibition.
