Osmosis and Diffusion

Front

What is osmosis?

Back

The diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water moves out of it.

Front

What is a semi-permeable membrane?

Back

A barrier that allows certain molecules to pass through while blocking others.

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 occurs when salt is poured on eggplant?

Back

Water will move out of the eggplant cells, causing the cells to shrink.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is equilibrium in the context of diffusion?

Back

A state where the concentration of molecules is equal throughout a space.
