OSMOSIS
Copy the pictures below, and write the correct type of solution underneath (isotonic, hypertonic, or hypotonic) Hypotonic Hypertonic Isotonic
Hypertonic means there is a GREATER concentration of solute molecules
OUTSIDE the cell than inside.
Hypo tonic means there is a LOWER concentration of solute molecules
OUTSIDE the cell than inside.
Isotonic means there is the SAME concentration of solute molecules outside the cell as inside.
The SWELLING AND BURSTING of animal cells when water enters is called cytolysis.
This happens when a cell is placed in a hypotonic solution.
The SHRINKING of plant cells when water leaves so the cell membrane pulls away from the cell wall is called plasmolysis.
It happens when a plant cell is placed into hypertonic solution.
The shrinking of ANIMAL cells that are placed in a HYPERTONIC solution is called crenation.
Cells stay the same size when placed in an isotonic solution because the amount of water leaving the cell is the same and the amount of water entering.
MULTIPLE CHOICE: Circle and/or fill-in the answer(s) that best completes the sentence.
The substance that dissolves to make a solution is called the ___________________ A. diffuser B. solvent C. solute D. concentrate
During diffusion molecules tend to move _____________________
A. up the concentration gradient
B. down the concentration gradient
C. from an area of lower concentration to an area of higher concentration
D. in a direction that doesn’t depend on concentration
When the concentration of a solute inside and outside a cell is the same, the cell has reached___________. A. maximum concentration B. homeostasis C. osmotic pressure D. equilibrium
The diffusion of water across a selectively permeable membrane is called ________________. A. active transport B. facilitated diffusion C. osmosis D.
