Diffusion
Substances move from a high to low concentration down a concentration gradient.
This is a passive process, which means that it does not need any energy.

Using the words diffusion, concentration gradient, oxygen and carbon dioxide, explain how the movement of gases occurs during photosynthesis in the leaf.
6
Osmosis
Water moves from a high to a low concentration across a partially permeable membrane and down a concentration gradient.
This is a passive process, which means that it does not need energy.
Osmosis is a type of diffusion.

Osmosis
HYPERtonic - if the concentration of the solutes in the solution outside of the cell is higher than inside.
HYPOtonic - if the concentration of the solutes in the solution outside of the cell is lower than inside.
ISOtonic - the solution of the solutes in the solution outside of the cell is the same as inside.

Active Transport
Substances move against a concentration gradient.
THIS IS NOT A PASSIVE PROCESS!
Energy is required for active transport to occur!
