Question

what is the difference between passive transport and diffusion? ​

Answer 1

hey mate here is your answer-------------------

Diffusion is a kind of passive transport. So the term "passive transport" is normally meant wider than just "diffusion". The meaning of passive is that the transport does not require active energy supply, and the transport is driven by the natural thermodynamical (downhill) gradient of the transported compound itself. In biology so called facilitated diffusion is common, and it usually means that the cell membrane contains transport channels (that doesn't require energy - ie NOT pumps) that simply stimulates diffusion by their presence. The degree of facilitation can be regulated, but there is no power supply involved.

hope it will help you :)
