... Osmosis is a special kind of diffusion. Only water can move by osmosis. ... Osmosis is the movement of water from a region of high concentration to a region of low concentration down a water concentration gradient. ... Water enters into the cell through its semi-permeable membrane by osmosis down a water potential gradient. ...
For plant cells water potential is a combination of solute potential and pressure potential:

When a plant cell is placed in a solution with a lower water potential, water will leave the cell by osmosis down a water potential gradient. ... Water moves into the plant cell by osmosis down a water potential gradient to achieve equilibrium to the solute. ... Water would move by osmosis out of the plant cell into the solution down a water potential gradient. ... This caused water to move from the solution into the plant cells by osmosis down a water potential gradient. ... Water moved by osmosis into the solution by osmosis down a water potential gradient. ... The plant cell is placed in a solution with a lower water potential, water will leave the cell by osmosis down a water potential gradient. ... This must be kept the same because the amount of surface area exposed to the solution may affect the rate of osmosis. ... This will allow us to see whether osmosis has taken place, and to what extent.
