Cell Transport Vocab

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell forms a vesicle around unwanted particles and expels it out of the cell.

Front

Where is there a low concentration of dye in a cup?

Back

At the bottom of the cup.

Front

What is true about Active Transport?

Back

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

Front

True or False: In Passive Transport, energy is required.

Back

False. Passive transport does not require energy.

Front

In Passive Transport, substances move from:

Back

High concentration to low concentration.

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

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

Front

Define Diffusion.

Back

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

Front

What is Osmosis?

Back

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

Front

What is a Concentration Gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.
