Front

The movement of water through a semi-permeable membrane is called ___________.

Back

Osmosis

Front

Does active transport require ATP?

Back

Yes

Front

Particles get in and out of a cell by passing through the __________.

Back

Cell membrane

Front

True or false. Passive transport does not need energy to happen.

Back

True

Front

Which type of transport can get rid of cellular wastes?

Back

Exocytosis

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 passive transport?

Back

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

Front

Define 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 role do protein pumps play in active transport?

Back

They help move substances across the cell membrane against their concentration gradient using energy.
