Cells
Diffusion
Molecules move randomly because of the
energy they have. Diffusion is the
movement of molecules from an area of
high concentration to an area of low
concentration (net movement). Example:
the diffusion of oxygen into the cells of
the body from the blood stream as the
cells are respiring (and using up oxygen).
Osmosis
This is a special type of diffusion that
only occurs with water. It's molecules also
move randomly requiring no energy form
the cell. Osmosis can only occur across a
partially permeable membrane from a
dilute solution to a more concentrated
solution.…read more
