diffusion and osmosis

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypotonic solution?

Back

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

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 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 the main difference between diffusion and osmosis?

Back

Diffusion refers to the movement of all types of particles, while osmosis specifically refers to the movement of water.

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 concentration gradient?

Back

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

Front

What does it mean for a solution to be hypertonic?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

What does it mean for a solution to be hypotonic?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.
