Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. For. e.g. Red blood cells shrink when placed in salt solution. it is all the result of plasmolysis

In botany and zoology, crenation refers to the leaf-like scalloped edges of an object such as a leaf or a shell. In biology, crenation describes the formation of abnormal notched surfaces on cells as a result of water loss through osmosis.
Cells are usually in an isotonic solution inside the body, meaning that there is the same concentration of solute and water both inside and outside the cells. This equilibrium allows the cells to keep their shape, with water moving in and out at a constant rate and maintaining the sameosmotic pressure across thesemipermeable membrane. However, when this equilibrium is disrupted by the presence of a higher concentration of solute in the solution, it creates a hypertonicenvironment, which causes the intracellular water to diffuse out. The cells start to shrivel and form abnormal spikes and notches on the cell membrane. This process is called crenation.
