Study Notes

Osmotic Pressure

Osmotic pressure is the pressure that develops in a solution when it is separated from a pure solvent by a semipermeable membrane.
Osmotic pressure increases with an increase in solute concentration.

Imbibition

Imbibition is the phenomenon through which plant cell walls absorb water.
Cellulose in tissue papers is responsible for the ability of tissue papers to absorb water through imbibition.
When plant cell walls absorb water through imbibition, they swell.

Hydrophilic Colloidal Substances

Examples of hydrophilic colloidal substances in plants include pectin, gums, and mucilages.

Key Factors

The main factor that determines osmotic pressure is solute concentration.
