Diffusion and Osmosis

Front

What is an isotonic solution?

Back

A solution in which the concentration of dissolved substances is equal to that inside a cell.

Front

What is diffusion?

Back

A type of passive transport involving the movement of substances from a high concentration area to a low concentration area.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space or between two solutions.

Front

What does the prefix 'hypo' mean?

Back

It means 'lower' than normal.

Front

What is passive transport?

Back

Movement across the cell membrane that does not require energy from the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of a cell.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is equilibrium in the context of diffusion?

Back

A state where the concentration of a substance is equal throughout a space.

Front

What is active transport?

Back

Movement of substances across a cell membrane that requires energy.

Front

What is the role of the cell membrane in diffusion?

Back

It acts as a barrier that selectively allows substances to pass through.
