plasma membrane

... OUT of the cell (from a higher concentration to a lower concentration - osmosis) and so the cell shrinks. The shrinking of the cell is called crenation in animal cells, and plasmolysis in plant cells. A hypotonic solution has a higher concentration of water than the cell, therefore there is ...
