Osmosis

Cards (8)

  • osmosis is the diffusion of water from a dilute solution to concentrated solution through a partially permeable membrane
  • dilute solutions have a high concentration water
  • in concentrated solution contain a low conc. of water
  • partially permeable membranes let some molecule pass through but not all of them
  • placing an animal cell in water
    • the cytoplasm of cells have a relatively low conc. water as they are already concentrated solutions, so if we place the cells in water osmosis will take place where water will move in the cell causing the cell to expand and maybe burst
  • placing an animal cell in a concentrated solution
    water will move out the cell through osmosis causing it to shrink
  • placing a plant cell in water
    water will move into into the cell causing it to expand but the cell wall will prevent it from bursting but it will still swell which is called a turgid cell
  • placing a plant cell in a concentrated solution
    water moves out from the cell through osmosis causing it to shrink making the cell flacid
