Passive Transport
Passive transport is the fundamental movement of ions and other molecular substances within the cells along the concentration gradient, without any external energy. It is also known as passive diffusion.
There are four types of passive transport:
- Simple Diffusion
- Facilitated Diffusion
- Filtration
- Osmosis
