Question

Can there be osmosis without diffusion? Diffusion without osmosis?

Answer 1

There can be no osmosis without diffusion because water DIFFUSES from a hypotonic solution to a hypertonic one (lower concentrated solution to a higher concentrated solution). But there can be diffusion without osmosis because there are different types of diffusion such as facilitated diffusion. I guess you can sort of say that osmosis is a kind of diffusion concerning water whereas simple diffusion does not concern water but concerns other substances such as oxygen. Um...don't know if this answers your question or if this is the kind of answer you're looking for, but goodluck!
