Which is true of simple diffusion of water?

#Section 2: General Biology
  1. Water usually exits a cell and produces a tremendous osmotic pressure.
  2. Water usually leaves the cell and produces negative osmotic pressure
  3. Water tends to enter and leave the cell equally, resulting in no pressure in the cell.
  4. Water usually enters a cell and produces a tremendous osmotic pressure AND the diffusion ultimately relies on the selectively permeable nature of the cell membrane.
