FLASHCARD QUESTION

Front

What is Passive Transport?

Back

Passive Transport is the movement of molecules across a cell membrane without the use of energy, moving from an area of high concentration to an area of low concentration.

3.

FLASHCARD QUESTION

Front

Define Osmosis.

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

4.

FLASHCARD QUESTION

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance between two areas, which drives the movement of particles.

5.

FLASHCARD QUESTION

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move molecules across the cell membrane.

6.

FLASHCARD QUESTION

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell takes in materials by engulfing them in a membrane.

7.

FLASHCARD QUESTION

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane.
