DIFFUSION AND OSMOSIS

Front

What is osmosis?

Back

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

Front

Define diffusion.

Back

The process by which molecules move from an area of high concentration to an area of low concentration.

Front

What is selective permeability?

Back

The property of a membrane that allows some molecules to pass through while blocking others.

Front

During osmosis, what direction does water move?

Back

Water moves from an area of high concentration to an area of low concentration.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while restricting others.

Front

Explain 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 happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst.

Front

What is equilibrium in the context of diffusion?

Back

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

Front

What role does energy play in osmosis?

Back

Osmosis is a passive process and does not require energy.
