  • Selective Permeability

    The membrane's ability to choose what enters or leaves the cell.

  • Proton Pump

    Uses energy to push hydrogen ions across a membrane to create a charge .

  • Osmosis

    The movement of water from where there is a lot of water to where there is less.

  • Hypertonic

    • Having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.

    • Cells shrinking

  • Hypotonic

    • Having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.

    • Cells swell

  • Isotonic

    • Equal concentration

    • Denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.

  • Turgid

    • Swollen or firm

    • Normal for plants

  • Flaccid

    • Limp or soft

    • To look or feel unpleasant

  • Plasmolysis

    The cell membrane shrivels and pulls away from the cell wall.

  • Peripheral Protein

    Proteins that are loosely attached to the exterior or interior surfaces of cell membranes, playing a crucial role in various cellular functions.

  • Integral Proteins

    Referred to as an integral membrane protein, is any protein which has a special functional region for the purpose of securing its position within the cellular membrane.
