Cell Movement Test

Front

What is Active Transport?

Back

The movement of molecules in and out of the cell membrane that requires energy.

Front

What is Passive Transport?

Back

The movement of particles from high to low concentration without the use of energy.

Front

What happens to a person's tongue cells after eating salty food?

Back

The cells get smaller due to osmosis.

Front

What is the function of the cell membrane?

Back

To control what enters and exits the cell.

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses proteins to help move molecules across the cell membrane.

Front

Define Osmosis.

Back

The movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy to move molecules against their concentration gradient, while Passive Transport does not.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the role of proteins in cell transport?

Back

Proteins assist in the movement of molecules across the cell membrane, especially in facilitated diffusion.

Front

What is concentration gradient?

Back

The difference in concentration of a substance across a space.
