If there is a weaker solution outside, water As the cell becomes turgid the cell wall exists a enters the cell by osmosis, moving down its 'wall-pressure'. This resists further concentration gradient. The cell does not water entry by osmosis. The turgidity of the cell resist the entry of water, as there is little or gives support to non-woody organs of a plant. no 'wall-pressure'
