Cell Transport

Front

What is osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What are molecules?

Back

Very small particles that compose all matter.

Front

What does isotonic mean?

Back

A solution with the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What does hypertonic mean?

Back

A solution with a higher concentration of solutes compared to another solution, causing water to exit the cell.

Front

What does hypotonic mean?

Back

A solution with a lower concentration of solutes compared to another solution, causing water to enter the cell.

Front

What is homeostasis?

Back

The process by which living organisms maintain a stable internal environment.

Front

What is active transport?

Back

The movement of molecules across a membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is endocytosis?

Back

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

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of solutes is equal inside and outside the cell.
