-the ability to move material through the plasma membrane is critical for cells.

-the type of membrane transport diffusion of water.

-diffusion of water across a semipermeable membrane (typically that membrane is the plasma membrane of a cell and there are several factors factors that affect its permeability).

• Interphase

• Osmosis

• Diffusion

• Concentration

-thing dissolved in water

-molecules in a state of high concentration want to move into a state of lower concentration.

• Osmosis

• Concentration

• Diffusion

• Solution

-water (H2O) will always prefer to move towards the area with higher solute concentration.

• Solvent

• Solute

-dissolves in solvent/ a dissolved substance.

-solutes dissolve in this/ able to dissolve substances.

• -can be osmotic, chemical, or solvent action.
