Back

The tails.

Front

What model describes the arrangement of the cell membrane as bendable and made of many parts?

Back

The Fluid Mosaic Model.

Front

What is the major difference between passive and active transport?

Back

Active transport uses energy; passive transport does not.

Front

What is the process called when cells form a vesicle to take in materials?

Back

Endocytosis.

Front

How do you classify a solution that has a lower concentration of solutes compared to the inside of a cell?

Back

The solution is hypotonic.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a membrane via specific transmembrane integral proteins.

Front

What does it mean if a solution is hypertonic?

Back

It has a higher concentration of solutes compared to the inside of a cell.

Front

What is exocytosis?

Back

The process by which a cell expels materials in vesicles.
