Osmosis makes the plant suck up water from the soil or the groundwater to use it in photosynthesis. Although most of the water goes waste in transpiration but osmosis has many advantages. There is an ascent of sap, nutrients and minerals are provided to the cells. The leaves stay turgid and do not wilt in the presence of water. The plant grows healthy and it helps in keeping the temperature of the plant cool. Moreover, cell to cell osmosis and increased root pressure demands for more water uptake along with other minerals.
