Question

1. this cell is in a solution. * hypotonic hypertonic isotonic

Explanation:

• In an isotonic solution, the concentration of solutes (represented by the yellow squares) is the same inside and outside the cell. There is no net movement of water across the cell membrane as the osmotic pressure is balanced.
• In a hypotonic solution, the solute concentration outside the cell would be lower than inside, causing water to rush into the cell (cell would swell).
• In a hypertonic solution, the solute concentration outside the cell is higher than inside, causing water to move out of the cell (cell would shrink).

Since the solute concentration appears equal inside and outside the cell in the diagram, it is an isotonic solution.

Answer:

isotonic
