What is osmosis?

Back

Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What does permeable mean?

Back

Permeable means that things can pass through.

Front

What is active transport?

Back

Active transport is the movement of molecules across a membrane using energy, usually against a concentration gradient.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a membrane without the use of energy, typically along a concentration gradient.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain substances 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 is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.

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.
