Diffuses when water is needed inside of the cell. It usually happens by a hyper-tonic or hypo-tonic solution. Wherever there is a high and low.. water diffuses. Water usually diffuses high to low.

Water or any substance that has the ability to diffuse always diffuses from a high concentration to a low concentration. Through a cell memrane, it's the same thing. When we drink water, we gulp down a whole mouthfull. When it's time for it to diffuse, it goes into different cells. We drink in a high c. and the water goes in the cells in low concentration. Same thing when the water wants to come out. It goes to another place that needs it.

Molecules that can diffuse across the membrane?

Small, nonpolar molecules like oxygen, carbon dioxide, and ethanol can easily diffuse across the cell membrane due to their ability to pass through the lipid bilayer. Water can also diffuse across the membrane, albeit at a slower rate, through specialized channels called aquaporins.

What can diffuse directly across the plasma membrane of a eukaryote cell?

Most small non polar molecules can diffuse across the membrane. Water is polar but diffuses across the cell through aquaporins. There are also proteins that actively transport substances across the cell membrane such as ions (ex.The Na/K pump). It can get a little confusing. I tried to be as simple as possible. I don't know if this is what you were looking for.

Occurs when water molecules diffuse through a membrane?

Osmosis. This is the movement of water molecules from an area of high water concentration to an area of low water concentration across a semi-permeable membrane.

Can oxygen diffuse across a cell membrane?

No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
