Chapter 4 THE WATER CYCLE

BIOLOGICAL SIGNIFICANCE OF OSMOSIS
  • Water from soil solution is absorbed into the root of plants by osmosis.
  • Water moves from one living cell to another. i.e. From root to stem to leaves by osmosis.
  • Osmosis helps plant cells retain water and keep their shape and turgidity.
  • Osmosis controls the opening and closing of the stomata.
  • In animals, blood and other body fluids must be maintained at the same osmotic pressure as the body cells.
