Cell Transport Vocab

Front

What is Exocytosis?

Back

Exocytosis is the process by which particles are removed from a cell by being pushed out through the cell membrane.

Front

What is Active Transport?

Back

Active transport is the movement of materials across a cell membrane using energy, moving substances from low concentration to high concentration.

Front

True or False: Active transport requires energy.

Back

True

Front

What is the main characteristic of Active Transport?

Back

Active transport requires energy to move substances against their concentration gradient.

Front

In Active Transport, substances move from:

Back

Low concentration to high concentration.

Front

What is Passive Transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving substances from high concentration to low concentration.

Front

What is Diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane.

Front

What does it mean for a membrane to be Permeable?

Back

A permeable membrane allows certain substances to pass through while blocking others.
