Question

What is the process of Imbibition involving?
A. Only diffusion
B. Only capillary action
C. Both A and B
D. None of the above

Answer 1

Hint: The procedure of Imbibition is very different from diffusion. In Imbibition, plants absorb water that causes swelling of the plant cell. Thus, we can define that the process of Imbibition is the procedure of absorption of the solid particles of an absorbent without forming a solution.

Complete answer:
Imbibition is a process of absorption of water by solid particles of a substance without forming a solution.
The substance which absorbs the water is called imbitants, and the liquid is called imitate. For the imbibition process to occur, the imitate needs to be hydrophilic as a hydrophobic substance cannot imbibe. Imbibition plays an essential role in the growth and development of plants.
For example:
Seed germination is the initial stage of plant growth.
Absorption of water by roots.
Water moves into the root hair by the process of Imbibition.
It helps to keep the cell moist.
CAPILLARY ACTION: It refers to the movement of a liquid through a narrow space. Plants use this capillary action to bring water up the roots and stem from the plant's rest.
None of the above, as the process of Imbibition, involves the only absorption.
Diffusion and capillary action do not play any role in the imbibition process.
So, the correct answer is “Option D”.

Additional Information:
The factor which helps in the process of imbibitions are
-Water potential gradient
-Increase in temperature increases the imbibition process
-There should be some attraction between imitate and imbitate.

Note:
The solid substances which take part in the imbibitions process are called Imbibes. The liquid which is absorbed is called imbitate. It is the first step of seed germination. Seedling came out of the soil due to imbibitional pressure. The uptake of the water by the solid substances without forming a solution is called Imbibition. The process of Imbibition occurs through a force called imbibition pressure.
