Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Pressure inside a cell that pushes the cell membrane outward into the cell wall. This occurs when more water enters into the cell.
A
Turgor
B
Monocarpic growth
C
Respiration
D
Photosynthesis
Explanation: 

Detailed explanation-1: -Water pushes the cellular membranes against the cell wall of the cell, causing turgor pressure. Whenever turgor pressure is high, the cell’s membrane put pressure on the cell wall, resulting in turgidity. The cell becomes flaccid when the turgor pressure is low.

Detailed explanation-2: -Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall. It is also called hydrostatic pressure, and is defined as the pressure in a fluid measured at a certain point within itself when at equilibrium.

Detailed explanation-3: -When water enters the cell of a plant cytoplasm and exerts an outward pressure and that pressure is called turgor pressure.

Detailed explanation-4: -Turgor pressure is the hydrostatic pressure in excess of ambient atmospheric pressure which can build up in living, walled cells. Turgor is generated through osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma membrane.

Detailed explanation-5: -When water moves into a cell by osmosis, osmotic pressure may build up inside the cell. If a cell has a cell wall, the wall helps maintain the cell’s water balance. Osmotic pressure is the main cause of support in many plants.
