Hypertonic Solution: Plant Cell
Plasmolyzed
Hypertonic Solution: Animal Cell
Shriveled
Hypotonic Solution: Plant Cell
Turgid
Due to the cell wall, plant cells are relatively okay in this state.
Hypotonic Solution: Animal Cell
Lysis
if minor - just swelled... but lysis is a big risk!
Plasmolyzed
cytoplasm shrinks and membrane pulls away from cell wall when water leaves the cell (hypertonic solution and plant cell)
Animal Cell Tonicity
Plant Cell Tonicity
Hypertonic Red Blood Cells
Normal (isotonic) on left; shriveled on right (water leaves the cell)
Hypertonic Solution
Hypotonic Solution
Isotonic Plant Cells
Isotonic Red Blood Cells
Microscope: Hypertonic Red Blood Cells
Shriveled
Unhappy Red Blood Cells
Crenation
the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis - i.e. shriveling
Ghost Cells
Difficult to see fragments of cells (especially studied with red blood cells) that appear under a microscope if they have lysed from being in a hypotonic solution. The shell/floppy membrane is flat and hard to see.
