Since diffusion does not require the cell to expend ATP, therefore, diffusion is considered a type of PASSIVE TRANSPORT.
PASSIVE TRANSPORT:
- Passive transport is a form of cellular transport in which substances move without the need of energy in form of ATP.
- The types of passive transport we have are diffusion, osmosis, facilitated diffusion etc.
