Osmosis, Diffusion, and Active Transport in Cells
Diffusion
Osmosis
Small molecules Oxygen and Carbon Dioxide and
others
No Energy Required
Water Only Water moves to dilute concentrated
solutions
Moves from high concentration to low
concentration
Moves material across cell membrane
Can be reversed through Active Transport
Can be reversed through Active Transport
Large Particles Requires Energy
