Question

difference between turgidity and flaccidity

Answer 1

Thanks for asking the question.
Flaccidity means low water potential. It is a condition in hypertonic environment when there is low water concentration in the cell s compared to the outside environment. So, the water moves outward making the cell flaccid. On the other hand, Turgidity means high water potential. It is the condition of high water concentration in cell as compared to the outside environment. This makes the cell turgid.
Hope it helps.

Answer 2

The mechanism by which water molecules move in and out of the cell through its plasma membrane is known as osmosis. The two types of osmosis are endosmosis and exosmosis. Endosmosis is the process by which water enters the cell. On the other hand, exosmosis is the movement of water out of the cell. The tonicity of the cytoplasm and surrounding solution determines the direction of the water movement. Tonicity is the effective osmotic pressure gradient defined by the water potential of the two solutions. Hypertonic, isotonic, and hypotonic are the three types of solutions that cause different tonicities. Turgidity and flaccidity are two conditions that occur depending on the tonicity. The main difference between turgidity and flaccidity is that turgidity is caused by the movement of water into the cell by endosmosis when it is placed in a hypotonic solution whereas flaccidity is caused by the movement of water out of the cell by both endosmosis and exosmosis when it is placed in an isotonic solution.
