Osmosis: water moves across a partially permeable membrane from and area of HIGH to LOW concentration.
Osmosis + Diffusion: Diffusion is the movement of any particles from an area of high to low concentration , however Osmosis only refers to the movement of water molecules.

Osmosis in animals, The solution outside of the cell must remain balance or risk harming the concentration gradient, causing the cell to shrivel or burst. Water moves in and out of the cell by osmosis to control this.
Osmosis in Plants, the plant cells use osmosis to make the plant cells swell and keep them rigid. This means that the fluid on the outside of the cells must always have a higher concentration to make sure the insides don't loose water
