Diffusion and Osmosis (2)

Front

What is diffusion?

Back

Diffusion is the natural movement of molecules from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semi-permeable membrane.

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane regulates what enters and leaves a cell.

Front

How do molecules move during diffusion?

Back

Molecules move from areas of high concentration to areas of low concentration.

Front

What happens to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

Water moves into the cell, causing it to swell and possibly burst.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain molecules to pass through while blocking others.

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is the state where the concentration of molecules is equal on both sides of a membrane.

Front

What is the main difference between diffusion and osmosis?

Back

Diffusion involves the movement of all types of molecules, while osmosis specifically involves the movement of water.

Front

What is a concentration gradient?

Back

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