Cell Transport

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

Movement of particles from low to high concentration that requires energy.

Front

What is Osmosis?

Back

A form of passive transport specifically for water molecules moving from high to low concentration.

Front

What drives the process of Diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

During Osmosis, what moves across the cell membrane?

Back

Water molecules.

Front

What is the main difference between Passive and Active Transport?

Back

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

Front

What is a concentration gradient?

Back

The difference in concentration of a substance between two areas.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and may shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell gains water and may swell or burst.

Front

What is facilitated diffusion?

Back

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