Question

Positive hydrostatic pressure is called turgor pressure.
a) true
b) false

Answer 1

Hint: The turgor pressure is the force that is present within the cell. It pushes the plasma membrane against the cell wall. The turgor pressure is responsible for making the plant tissue rigid in nature. If there is a loss of turgor pressure then the flowers and leaves will wilt.

Complete answer:
The hydrostatic pressure is the pressure which is exerted by the fluid at equilibrium due to the force of gravity. If the pressure is exerted in the force of gravity then it is called positive hydrostatic pressure and when the force is exerted in the opposite direction to that of the gravity then it is called negative hydrostatic pressure. The turgor pressure is the force that acts within the cell of an organism. The turgor pressure is responsible for pushing the plasma membrane against the cell wall. It exerts a positive hydrostatic pressure. So, the turgor pressure is also known as hydrostatic pressure. The turgor pressure helps in providing the structural support to the cell and as tissue to the whole tissue structure. It helps in making the plant rigid or providing it with its rigidity. In the absence of the turgor pressure in the plant cell membrane, the cell would lose its rigidity and would become flaccid.

So, the answer is ‘true’.

Note: The turgor pressure is also known as the hydrostatic pressure. The presence of the turgor pressure provides the plant with its rigidity. This rigidity gives the plants its structure. If the turgor pressure is absent from the plant then it may lead to wilting of the leaves and the flowers.
