Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is turgor?
A
Water moving through the plant and stiffening the cells to provide support
B
Water in the plant
C
Movement of nutrients within the plant
D
Movement of sugars within the plant
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Turgid pressure is a type of force that is caused by the plasma membrane pushing against the cell walls of a plant cell. This pressure is created when the central vacuole fills completely full of water and adds volume to the plasma of the cell. Water levels are controlled with osmosis.

Detailed explanation-3: -Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.

Detailed explanation-4: -Turgidity is the state of being turgid or swollen, especially due to high fluid content. In a general context, turgidity refers to the condition of being bloated, distended, or swollen.

Detailed explanation-5: -Turgidity is the state in which the cell wall is fully stretched and cannot accommodate any more water. The pressure of the cell contents on the cell wall is called turgor pressure.
