Key Topics to Revise

1

Importance of Water and Minerals

  • Water forms a large part of protoplasm.
  • Plants generally have more water than animals.
  • Water helps in opening and closing of stomata by providing turgidity.
2

Imbibition and Diffusion

  • Imbibition is the adsorption of water molecules by dry hydrophilic colloids due to surface attraction.
  • Imbibition occurs along the diffusion gradient.
  • Maximum imbibition occurs in agar-agar, protein, pectin and cellulose.
3

Membranes and Osmosis

  • A permeable membrane allows both solute and solvent molecules to pass through.
  • A semi-permeable membrane allows only water molecules to pass through.
  • A selectively or differentially permeable membrane allows water and some selected solute molecules to pass through.
4

Endosmosis, Exosmosis and Tonicity

  • Endosmosis is the inward movement of water into a cell placed in a hypotonic solution.
  • Endosmosis makes the cell turgid.
  • Exosmosis is the outward movement of water out of a cell placed in a hypertonic solution.
