Question

1. osmosis (water movement)

. osmosis = water movement.
. hypotonic: water in, cell swells.
. hypertonic: water out, cell shrinks.
. isotonic: balanced.

review questions:
. what happens to a cell in saltwater?
. which solution makes a cell swell?

Explanation:

Saltwater is typically hypertonic to cells. In a hypertonic solution, water moves out of the cell causing it to shrink. A hypotonic solution has a lower solute - concentration than the cell, so water moves into the cell, making it swell.

Answer:

• What happens to a cell in saltwater? The cell shrinks as water moves out (since saltwater is usually hypertonic).
• Which solution makes a cell swell? A hypotonic solution makes a cell swell as water moves into the cell.
