Types of Membranes

Impermeable= Impossible to pass

Permeable= Permission to pass

Semi-permeable=Some can pass.

Large Molecules

Membrane Proteins

molecular movement

Molecular movement

Osmosis is the movement of WATER from high to low concentration.

Flies = representing water molecules

Small

Bird= Representing sugar molecules

Cell membrane (CAGE)

types of concentrations
Types of Concentrations
  • Isotonic -Iso means (same). The cell is in a normal state. Same amount of water and solutes in and out of the cell.
  • Hypotonic - The cell swells because more water goes in the cell. Less solutes outside of the cell, high concentration of solutes in the cell, so water moves in.
  • Hypertonic- The cell shrinks because water leaves the cell. High concentration of solids on the outside of the cell, so the cell loses water and shrinks.
