Which of the following best describes a solute?

• The substance that dissolves another substance

• The substance that is dissolved in a solution

• The liquid part of a solution

• The gas in a solution

What is a solvent?

• The substance that is dissolved

• The substance that does the dissolving

• The solid in a solution

• Hypotonic

• Supersonic

Which direction does water move during osmosis?

• From high solute concentration to low solute concentration

• From low water concentration to high water concentration

• Towards the higher concentration of solutes

• From high pressure to low pressure

If a cell is placed in an isotonic solution, what will happen to the movement of water?

• Water will only move into the cell

• Water will only move out of the cell

• Water will move in and out at equal rates

• Water will not move at all

Explain what would happen to an animal cell placed in a hypotonic solution.

• It would shrink due to water loss

• It would swell and possibly burst due to water gain

• It would remain unchanged

• It would become turgid

A plant cell is placed in a hypertonic solution. Predict what will happen to the cell.

• It will become turgid

• It will lose water and the cell membrane will pull away from the cell wall

• It will burst

• It will remain unchanged
