Diffusion and Osmosis

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrink.

Front

What is equilibrium in the context of cells?

Back

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

Front

What does 'high concentration area' mean?

Back

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

Front

What is a selectively permeable membrane?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to shrink.

Front

What is the role of energy in diffusion?

Back

Diffusion is a passive process and does not require energy; molecules move naturally due to concentration gradients.
