Diffusion and Osmosis

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What does 'high concentration area' mean?

Back

A high concentration area means that the molecules are tightly packed together.

Front

What is osmosis?

Back

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

Front

What happens during osmosis?

Back

During osmosis, water moves from high to low concentration.

Front

What is equilibrium in the context of cells?

Back

Equilibrium is the state when the concentration of water inside and outside of a cell is equal.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain molecules to pass through while blocking others.

Front

What is a concentration gradient?

Back

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

Front

What is the role of energy in diffusion?

Back

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

Front

What is hypertonic solution?

Back

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

Front

What is hypotonic solution?

Back

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