Cell Transport

Front

What is concentration?

Back

The amount of particles in a given space.

Front

What is passive transport?

Back

The diffusion of particles through the cell membrane from high to low concentration.

Front

What does 'high concentration area' mean?

Back

Tightly packed together.

Front

What happens when you put a plant in water?

Back

It will swell because water diffuses into the cells.

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

The diffusion of water through a selectively permeable membrane.

Front

What is active transport?

Back

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

Front

What is a permeable membrane?

Back

A membrane that allows certain substances to pass through.

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes outside the cell, causing the cell to shrink.
