Osmosis
Define osmosis: __________________________________________________________________
In which direction does water move across membranes; up or down the concentration gradient?
___________________________________________________________________
Define these 3 terms:
Hypotonic:
___________________________________________________________________
Hypertonic: ___________________________________________________________________
Isotonic: ___________________________________________________________________
Use arrows to show the direction of water movement into or out of each cell. Color and label the cell in
an isotonic environment light blue, the hypotonic environment yellow, and the hypertonic environment
light green.
Match the description or picture with the osmotic condition:
A. Isotonic
B. Hypertonic
_____ solution with a lower solute concentration
_____ the solute concentration is the same
C. Hypotonic
_____ red blood cell bursts (cytolysis)
_____ plant cell with good turgor pressure
_____ solution with a higher solute concentration _____ plant cell loses turgor pressure (Plasmolysis)
_____ condition that animal cells require
_____ solution with a high water concentration
