Q. Read the given statements and select the correct option.
Statement 1 : It becomes difficult to open and shut the wooden doors and windows during rainy season.
Statement 2 : Wooden doors and windows imbibe water in rainy season and thus their volume is increased.

Transport in Plants

Solution:

Wooden doors and windows adsorb water in humid rainy season and increase in their volume so that they are hard to open or close. If a dry piece of wood is placed in water, it swells and increases its volume. During imbibition, the water molecules get tightly adsorbed and become immobilised.
