Back

Yes

Front

What type of organelle is used during endocytosis and exocytosis?

Back

Vesicle

Front

Which type of movement requires cellular energy?

Back

Active transport

Front

Define 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

Define passive transport.

Back

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

Front

What is osmosis?

Back

The diffusion of water molecules through a semi-permeable membrane.

Front

What is diffusion?

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is facilitated diffusion?

Back

A process of passive transport that uses transport proteins to move molecules across the cell membrane.
