A
Diffusion is the net random movement of particles from an area of high concentration to and area of low concentration. This does not require any ATP
2
Q
What is the definition of osmosis
A
The net random movement of particles from an area of low water potential to an area of high water potential, across a partially permeable membrane. This does require ATP
3
Q
