Detailed explanation-1: -Hence, the correct answer is ‘Turgor pressure’.

Detailed explanation-2: -Note: Osmotic pressure refers to the minimum pressure that needs to be applied on the solution to prevent the inward flow of its pure solvent across a semipermeable membrane whereas turgor pressure refers to the pressure inside the cell pushes the plasma membrane against the cell wall of the plant cell.

Detailed explanation-3: -The pressure exerted by the osmotic flow of water is called turgidity. It is caused by the osmotic flow of water through a selectively permeable membrane.

Detailed explanation-4: -turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.
