Exploring Diffusion and Osmosis Concepts

What is the initial step in solving an osmosis problem?

• Measure the temperature

• Draw the scenario

• Identify the solute

• Calculate the total concentration

In the first practice problem, where does the water move?

• Moves randomly

• Stays the same

• Into the cell

• Out of the cell

If a cell has 25% sugar inside, what percentage of water is inside the cell?

• 25%

• 50%

• 100%

• 75%

In the second practice problem, where does the water move?

• Moves randomly

• Stays the same

• Into the cell

• Out of the cell

What is dynamic equilibrium?

• When only water molecules move

• When the rate of molecules moving in and out of the cell is equal

• When the cell bursts

• When molecules stop moving

Which factor does NOT affect the rate of diffusion?

• Color

• Concentration

• Temperature

• Pressure

What happens to a cell in a hypertonic solution?

• It stays the same

• It shrinks

• It grows

• It bursts

What is a hypotonic solution?

• When the cell shrinks

• When the solute concentration is equal inside and outside

• When the water concentration inside the cell is lower than outside

• When the water concentration inside the cell is higher than outside

In an isotonic solution, what happens to the cell size?

• It shrinks

• It bursts

• It grows

• It stays the same

In the final practice problem, where does the water move?

• Moves randomly

• Stays the same

• Into the cell

• Out of the cell
