Osmosis & Diffusion

This week in AP Biology we didn't really discuss about much because of a lab we are doing in class(which we still haven't completed), so we pretty much reviewed what we learned last week. But most parts in the lab is about osmosis and diffusion, which is something we talked about last week. Osmosis is the movement of water in a cell and diffusion is the movement between other materials in a cell. Without osmosis or diffusion, our body would not be able to transport all of the nutrients from the food we eat and drink.Both osmosis and diffusion have similarities and differences. For example diffusion occurs in a gaseous state while osmosis does not and diffusion moves from high to low and osmosis is vice versa. Like I said, we didn't discuss about a whole this week because of an important lab, but either way it was still interesting to talk about osmosis and diffusion in detail again.
