Osmosis and Diffusion

Front

What is osmosis?

Back

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

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and swell.

Front

What is diffusion?

Back

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

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 particles.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water and shrink.

Front

What role does energy play in osmosis?

Back

Osmosis does not require energy; it is a passive process.

Front

What is the concentration gradient?

Back

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

What happens to an egg placed in saltwater?

Back

The egg will lose water and shrink due to the hypertonic environment.
