When a red blood cell loses water by osmosis the shrinking of the cell volume leads to crinkling of the plasma membrane, called
Flacidity
Bursting
Crenation
Tonicity
C.
Crenation
When the external water potential is more negative than that of the cell, the cell lose water by osmosis. Such phenomenon in red blood cell is called crenation.
Flaccid cell in botany, is a cell in which the plasma membrane is not pressed tightly against the cell wall.
Bursting of cell occurs due to an osmotic imbalance that has caused excess water to diffuse into the cell.
Tonicity is a measure of the effective osmotic pressure gradient.
