Passive transport and Its Types (Chapter Transport and movement)

Passive transport is the type of transport in which substances, molecules, particles move from higher concentration to lower concentration without the need of energy.
It is very important topic of chapter Movement of substances / Cell membrane and transport.
In this video you will learn following concepts about passive transport.
1) What is passive transport
2) Types of Passive transport
3) Difference between Active and Passive transport
4) Simple diffusion
5) Facilitated Diffusion
6) Factors Effecting rate of Diffusion.
For better understanding the diffusion you can first watch the detailed video on cell membrane    • Cell membrane / Plasma Membrane Struc...
