Tonicity

Osmosis

Movement of water across a semipermeable membrane from an area of high water concentration to low

Hypertonic Solution

Higher solute concentration outside the cell

Hypotonic Solution

Lower solute concentration outside the cell

Isotonic Solution

Same solute concentration inside and outside the cell

Plasmolysis

Shrinking of a plant cell due to water loss in a hypertonic environment

Turgor Pressure

Pressure from the cell wall against the cell membrane in plant cells

Flaccid

A plant cell that has lost turgor pressure

Lysis

Bursting of an animal cell due to water intake in a hypotonic solution

Crenation

Shrinking of an animal cell in a hypertonic solution
