Exploring Osmosis Through Animation and Experiments

What is a solute in a solution?

• The substance that dissolves in a solvent

• The liquid in which a substance dissolves

• A type of solid

• A type of gas

In the osmosis experiment, what was observed over time?

• The level of solution on the left remained the same

• The level of blue solution on the right went up

• The level of solution on the left went up

• The level of blue solution on the right went down

What is osmosis?

• The diffusion of water across a semi-permeable membrane

• The movement of solutes from higher to lower concentration

• The diffusion of solutes across a membrane

• The movement of water from lower to higher concentration

During osmosis, water moves from an area of ______ solute concentration to an area of ______ solute concentration.

• equal; equal

• lower; higher

• higher; lower

• higher; higher

What is a simple way to remember the direction of water flow during osmosis?

• Water stays still

• Water moves randomly

• Water follows solvent

• Water follows solute

What does 'hypertonic' mean?

• A solution with a higher solute concentration

• A solution with equal solute concentration

• A solution with no solute

• A solution with a lower solute concentration

In a hypotonic solution, water will:

• Enter the solution

• Move randomly

• Leave the solution

• Stay the same

What happens to water movement between isotonic solutions?

• Water moves into both solutions

• Water moves out of both solutions

• Water movement is equal with no net change

• Water moves from one solution to another

What happened to the blood cells in a hypotonic solution?

• They changed color

• They popped

• They remained the same

• They shriveled up

Why did the egg shrink in the hypertonic corn syrup?

• It absorbed water

• It remained the same

• It gained solute

• It lost water due to osmosis
