What are two differences between facilitated diffusion and osmosis?

1 Answer

The material being transported and the membrane proteins involved in the process.


Facilitated diffusion refers to the diffusion of molecules into or out of cells. The term is general and can refer to many different types of molecules. For example, glucose can be transported into cells from the blood stream into cells by glucose transporter-4

Here is a video which explains how facilitated diffusion works:

Osmosis refers only to the transport of water into or out of cells. Osmosis can occur directly through the membrane of the cell, or through transport proteins called aquaporin.


Here is a video which describes how osmosis impacts onion cells placed into tap water and then into a salt water solution.
