The osmoprotective effect is called a series of responses that plants start when they are subjected to water stress to protect themselves from dehydration.

In short, at the cellular level, when the amount of water in the medium decreases, there is a flow of water from the cytoplasm to the outside of the membrane, producing a loss of turgor in the tissues and a decrease in the photosynthetic rate of the cell. . The plant begins to synthesize substances that compensate the concentration of solutes in the cytoplasm with that in the external environment and prevent excessive outflow of water from the cells.
