- Diffusion
- Diffusion is the movement of molecules from a region of high
concentration inside the cell to a region of low concentration
outside traveling down a concentration, this is a passive process
- Diffusion is the movement of molecules from a region of high
concentration inside the cell to a region of low concentration
outside traveling down a concentration, this is a passive process
- Active Transport
- Active transport is the movement of ions from a region of low
concentration inside the cell the region of high concentration
outside the cell, moving against the concentration gradient,
this process requires ATP energy
- Active transport is the movement of ions from a region of low
concentration inside the cell the region of high concentration
outside the cell, moving against the concentration gradient,
this process requires ATP energy
- Osmosis
- Osmosis is the movement of water molecules form a region of
high concentration inside the cell to a region of low
concentration outside the cell, travelling down a concentration
gradient, this is a passive process
- Osmosis is the movement of water molecules form a region of
