Cell Transport

Front

Why is diffusion and osmosis important to cells?

Back

It allows them to take in materials without using energy.

Front

Movement of particles from high to low concentration is called?

Back

Passive Transport.

Front

When particles move from areas of high concentration to areas less concentrated, this process is known as?

Back

Diffusion.

Front

What does 'high concentration area' mean?

Back

Tightly packed together.

Front

What does selectively-permeable mean?

Back

The cell controls what passes in and out of the cell.

Front

What is 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 active transport?

Back

The movement of particles against a concentration gradient, requiring energy.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

What is endocytosis?

Back

The process by which a cell takes in materials by engulfing them in a membrane.
