Cell Transport

Front

What is Active Transport?

Back

Movement of particles from LOW concentration to HIGH concentration with the use of ENERGY.

Front

What is Exocytosis?

Back

A process where a paramecium gets rid of waste by expelling materials out of the cell.

Front

What does Selectively Permeable mean?

Back

Allowing some substances to pass through while others cannot.

Front

What is the role of the Cell Membrane?

Back

It is responsible for allowing materials in and out of the cell.

Front

What is Diffusion?

Back

The movement of particles from an area of HIGH concentration to an area of LOW concentration without the use of energy.

Front

What is Osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane.

Front

What is Facilitated Diffusion?

Back

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

Front

What is the difference between Passive Transport and Active Transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is Endocytosis?

Back

The process by which cells take in substances by engulfing them in a membrane.

Front

What is a Concentration Gradient?

Back

A difference in the concentration of a substance across a space.
