particles moving from a high concentration to a low concentration

particles moving from a low concentration to a high concentration

water molecules moving into and out of a cell

water moving through the water cycle

diffusion

osmosis

selectively permeable

concentration

Diffusion because salt is moving

Diffusion because water is moving

Osmosis because salt is moving

Osmosis because water is moving

out of the cell

(there are more water molecules inside the cell than around it)

into the cell

(there are more water molecules around the cell than inside it)

the water molecules won't move because there is the same amount inside and outside of the cell

out of the cell

(there are more water molecules inside the cell than around it)

into the cell

the water molecules won't move because there is the same amount inside and outside of the cell
