The adsorption of water by hydrophilic compounds like cellulose and pectin in root hair cell wall is called . . . . . . .

Give scientific reasons:
$(1)$ Plasmolysis is possible in plant cells,while it is not possible in animal cells.
$(2)$ Doors and windows of a house swell during the monsoon season.

Imbibition is a very significant property of

$A$ special type of diffusion,which occurs when water is absorbed by solids causing them to increase in volume,is called:

Plant seeds,when sown in soil,germinate and emerge from it due to:

Absorption of water from soil by dry seeds increases the $ \text{imbibition pressure} $, thus helping seedlings to come out of soil.
