Cell Transport

Front

What is diffusion?

Back

Diffusion is the process by which particles move from an area of high concentration to an area of low concentration.

Front

What is passive transport?

Back

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

Front

What does 'high concentration area' mean?

Back

A high concentration area refers to a space where particles are tightly packed together.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

During osmosis, what direction does water move?

Back

Water moves from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration).

Front

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of any particles from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane is a barrier that allows certain substances to pass through while blocking others.

Front

What happens to a gummy bear in salt water?

Back

The gummy bear loses mass because water moves out of it due to osmosis.

Front

What is concentration gradient?

Back

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