Question

what do u mean by imbibition pressure in cell ?

Answer 1

Imbibition is a type of diffusion where the water is absorbed by the solid particles called colloids, without forming a solution causing an enormous increase in volume. To define, the absorption of water by hydrophilic colloids is known asimbibition

Answer 2

Imbibition is a type of diffusion where the water is absorbed by the solid particles called colloids, without forming a solution causing an enormous increase in volume. To define, the absorption of water by hydrophilic colloids is known as imbibition.


imbibition can be defined as the process by which non-living or living things absorb water.
so the pressure generated because of this absorption is k/a imbibition pressure.
If seeds doesn't absorb water so the seed coat will not rupture and the seed will not germinate.









I also wrote the difference of:-

Diffusion and Imbibition

1. Diffusion.

It refers to the movement of molecules, ions of solids, liquids or gases from the region of higher concentration to the region of lower concentration

1. Imbibition.

It refers to the absorption of water by general surface.

2. Diffusion.

It takes place in solids, liquids and gases.

2. Imbibition.

It takes place both in living and dead cells.

3. Diffusion.

It is not a reversible process.

3. Imbibition.

It is a reversible process.

4. Diffusion.

No need of semi-permeable membrane.

4. Imbibition.

An absorbent is involved but no membrane in it.
