WebThree terms—hypertonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell: If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher ... Web2.

Plasmolysis & Deplasmolysis Processes, Purposes

WebMeaning of Plasmolysis: Shrinkage of the protoplast of a cell from its cell wall under the influence of a hypertonic solution is called plasmolysis. Hypertonic solution causes exosmosis or withdrawal of water from cytoplasm and then the central vacuole of cell. The size of cytoplasm as well as central vacuole and hence protoplast becomes reduced. WebApr 10, 2024 · The complete process of plasmolysis can be understood in three stages.
