Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

What are TWO ways you can predict the movement of water?

• from a [High] of water to a [Low] of water

• towards the [Lower] of solutes

• towards the [Higher] of solutes

• from a [Low] of water to a [High] of water

Which option best describes what osmosis is?

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of any particle from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of any particle from an area of low concentration to an area of high concentration

The cell below is shrinking. It can be concluded that the concentration of water is:

• higher inside the cell than outside the cell

• lower inside the cell than outside the cell

• the same inside and outside the cell
