Question

How are osmosis and diffusion alike?

Answer 1

Osmosis and diffusion are alike, as osmosis is a special kind of diffusion.

Explanation:

Diffusion:

Diffusion is the process of where a substance moves from an area of high concentration to an area of lower concentration. Diffusion doesn’t need a membrane.

Osmosis:

Whereas, osmosis is a special kind of diffusion in which water moves through a selectively permeable membrane from an area of high concentration to an area of low concentration.

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