What to Focus On

  • Root hairs absorb water from the soil.
  • Capillary water is the main source of water for plants.
  • Apoplast pathway: through cell walls; Symplast pathway: through cytoplasm via plasmodesmata.
  • Diffusion: passive movement down concentration gradient.
  • Osmosis: diffusion of water through semi-permeable membrane.
  • Imbibition: initial water uptake in seeds; causes swelling.
  • Water potential (ψ) drives water movement; pure water = 0; solutions < 0.
  • Turgor pressure gives rigidity to non-woody plants.
  • Wilting occurs due to loss of turgor pressure.

Common Mistakes to Avoid

Water moves up the plant because of root pressure alone, especially in tall trees.

Osmosis and diffusion are the same because both involve movement from high to low concentration.

Plants absorb water mainly through the entire root surface, not just root hairs.

Memory Tips
