Types of Membranes

Impermeable= Impossible to pass

Permeable= Permission to pass

Semi-permeable=Some can pass.

Molecular movement

Molecular movement

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


Membranes and molecular movement

  • Diffusionis movement of solid molecules (solutes) from high to low concentration.

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.
