Unit 4 Vocab: Cell Transport

Front

What is the scientific definition of a Concentration Gradient?

Back

The difference in concentration across a space.

Front

What is the scientific definition of passive transport?

Back

The movement across the cell membrane that does not require energy.

Front

What is the process in which a molecule passes across the membrane through the cell membrane channels?

Back

Facilitated diffusion.

Front

What is a solution with a lower concentration of solutes than another solution?

Back

Hypotonic solution.

Front

What is the diffusion of water through a selectively permeable membrane?

Back

Osmosis.

Front

What is the role of the cell membrane in transport processes?

Back

The cell membrane regulates the movement of substances in and out of the cell.

Front

What is active transport?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What is a hypertonic solution?

Back

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

Front

What is isotonic solution?

Back

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