diffusion is the movement of molecules or stuff through the cell membrane
osmosis is the movement of water
water move from high contration to lower concentration
the there is salt outside of the cells the water will move out of the cell membrane and if there is salt inside the cells the water will move into the cell
Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.
