Question

for each illustration below, label it is one of the following: hypertonic, hypotonic, or isotonic. 11. 12. 13.

Explanation:

• In a hypotonic solution, water moves into the cell (as shown by the yellow arrows in 11), causing the cell to swell.
• In an isotonic solution, there is no net movement of water (green arrows in 12 show equal movement in and out).
• In a hypertonic solution, water moves out of the cell (green arrows in 13 show more water leaving), causing the cell to shrink.

Answer:

1. Hypotonic
2. Isotonic
3. Hypertonic
