Osmosis and Diffusion Review

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solute compared to the inside of the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane.

Front

What does 'high concentration area' refer to?

Back

It refers to a region where solute particles are tightly packed together.

Front

What happens to a cell in a hypotonic solution?

Back

A cell in a hypotonic solution will swell as water enters the cell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solute compared to the inside of the cell.

Front

What happens to an animal cell placed in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will shrink as water leaves the cell.

Front

Define diffusion.

Back

Diffusion is the movement of solute particles from an area of high concentration to an area of low concentration.

Front

What is the role of a selectively permeable membrane in osmosis?

Back

A selectively permeable membrane allows only certain molecules, like water, to pass through while blocking others.

Front

How does temperature affect the rate of diffusion?

Back

Higher temperatures increase the kinetic energy of molecules, leading to a faster rate of diffusion.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.
