What is Exocytosis?

Back

The process by which particles are removed from a cell by being pushed out.

Front

What is Endocytosis?

Back

The process by which a cell engulfs material from its environment, bringing it into the cell.

Front

Define Passive Diffusion.

Back

The movement of substances from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What is Osmosis?

Back

Diffusion of water through a selectively permeable membrane.

Front

What is a Hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water.

Front

What is a Hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to the inside of the cell, causing the cell to gain water.

Front

What is an Isotonic solution?

Back

A solution that has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is the role of the cell membrane?

Back

To control what enters and leaves the cell, acting as a barrier and a gatekeeper.

Front

What is facilitated diffusion?

Back

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

Front

What is active transport?

Back

The movement of molecules across a cell membrane against their concentration gradient, requiring energy.
