the cell's volume, while in an isotonic solution, water flows in and out of the cell at an equal rate.

Turgidity is the point at which the cell's membrane pushes against the cell wall, which is when turgor pressure is high. When the cell has low turgor pressure, it is flaccid. In plants, this is shown as wilted anatomical structures. This is more specifically known as plasmolysis.The volume and geometry of the cell affects the value of turgor pressure and how it can affect the cell wall's plasticity.
