Osmosis and Diffusion tennis 2024

Front

What is osmosis?

Back

The movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

The movement of molecules across a cell membrane from an area of lower concentration to an area of higher concentration, requiring energy.

Front

What is passive transport?

Back

The movement of molecules across a cell membrane without the use of energy, typically from an area of higher concentration to an area of lower concentration.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is an isotonic solution?

Back

A solution with the same concentration of solutes as another solution.

Front

How does osmosis differ from diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.

Front

What role do cell membranes play in osmosis and diffusion?

Back

Cell membranes are semi-permeable, allowing certain molecules to pass while blocking others, facilitating osmosis and diffusion.

Front

Why is a soap bubble like a cell membrane?

Back

It is thin, moves constantly, and is semi-permeable.
