Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>

The process of the plasma membrane pumping excess sodium out of a cell into an environment where there is a lower concentration
azamat

Answer:

The correct option is A. Diffusion

Explanation:

Diffusion can be described as a mechanism through which molecules move along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy as the molecules or ions move along the concentration gradient.

Hence, the pumping excess sodium ions by the cell membrane to an area where the concentration of sodium is less would be an example of diffusion.
