Osmosis Test

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What does permeable mean?

Back

Permeable means that things can pass through.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

Define diffusion.

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while restricting the movement of solutes.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent, forming a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.
