Question

1. in diagram 2, what will happen to the size of the cell? *

the cell will shrink
the cell will swell
the cell will stay the same size
osmosis diagram 3
0% solute
100% water
15% solute
85% water

1. in diagram 3, which term describes the solution outside of the cell? *

hypertonic
hypotonic
isotonic

Explanation:

• For question 41: Osmosis is the movement of water from an area of high water concentration (low solute) to an area of low water concentration (high solute). In diagram 3, the outside has 100% water (0% solute) and the cell has 85% water (15% solute). So water will move into the cell (from high water outside to low water inside the cell), causing the cell to swell.
• For question 42: A hypotonic solution has a lower solute concentration compared to the inside of the cell. Here, the outside solution has 0% solute (higher water concentration) and the cell has 15% solute. So the outside solution is hypotonic.

Answer:

1. The cell will swell
2. Hypotonic
