Osmosis V Diffusion F21

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

What happens to an animal cell in a hypertonic solution?

Back

The cell shrinks as water moves out of the cell to the area of higher solute concentration.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing the cell to swell as water enters.

Front

What is an isotonic solution?

Back

A solution with the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is a concentration gradient?

Back

The difference in the concentration of a substance across a space, which drives diffusion.

Front

What role does a semi-permeable membrane play in osmosis?

Back

It allows water to pass through while preventing the movement of solutes.

Front

What is the effect of placing a cell in a hypotonic solution?

Back

The cell will swell and may burst due to the influx of water.

Front

What is the primary 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 equilibrium in the context of diffusion?

Back

A state where the concentration of particles is equal throughout a space, resulting in no net movement.
