1. Water molecules diffuse from the soil into root hair by osmosis.
2. Cell to cell movement of water occurs by osmosis.
3. Opening and closing of stomata are due to osmotic changes in guard cells.
4. The flowers remain fully stretched due to osmosis.
5. The plant movements like nyctinasty, seismonasty etc. occur due to the changes in the osmotic pressure.
6. The cells remain fully turgid due to osmosis.
