Diffusion Practice

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Front

What is a hypotonic solution?

Back

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

Front

What is a hypertonic solution?

Back

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

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water moves out of the cell to balance the solute concentration.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell and may burst as water moves into the cell.

Front

What is the role of a semipermeable membrane in osmosis?

Back

A semipermeable membrane allows only certain molecules, like water, to pass through while blocking others, facilitating osmosis.

Front

How does concentration gradient affect diffusion?

Back

Molecules will move from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is equilibrium in the context of diffusion?

Back

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