Osmosis

    Cards (15)

    • What is osmosis?
      The diffusion of water through a membrane
    • What is the direction of water movement in osmosis?
      From dilute to concentrated solution
    • What type of membrane allows osmosis to occur?
      Partially permeable membrane
    • What happens to water in a dilute sugar solution?
      It has a high concentration of water
    • What happens in a concentrated sugar solution?
      It has a low concentration of water
    • What does a partially permeable membrane allow?
      Some molecules to pass through
    • What happens to water when a cell is placed in water?
      Water moves into the cell by osmosis
    • What effect does osmosis have on an animal cell in water?
      The cell expands and may burst
    • What happens to an animal cell in a concentrated solution?
      Water moves out, causing the cell to shrink
    • What happens to a plant cell in water?
      Water moves in, causing the cell to expand
    • Why doesn't a plant cell burst when it expands in water?
      The cell wall prevents bursting
    • What term describes a swollen plant cell?
      Turgid
    • What happens to a plant cell in a concentrated solution?
      Water moves out, causing the cell to shrink
    • What term describes a shrunk plant cell?
      Flaccid
    • What are the effects of osmosis on animal and plant cells?
      • Animal cells:
      • In water: expand and may burst
      • In concentrated solution: shrink
      • Plant cells:
      • In water: expand (turgid)
      • In concentrated solution: shrink (flaccid)
