What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane.

Front

Why is diffusion important for cells?

Back

Diffusion allows cells to take in materials/substances without using energy.

Front

What does selectively permeable mean?

Back

Selectively permeable means allowing certain things to enter and leave the cell.

Front

What is the end result of diffusion?

Back

The end result of diffusion is an even distribution of particles.

Front

What is an example of diffusion in everyday life?

Back

An example of diffusion is the smell of perfume spreading in a room.

Front

What factors affect the rate of diffusion?

Back

Factors include temperature, concentration gradient, and the size of the particles.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion involves all types of particles, while osmosis specifically involves water.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a membrane without the use of energy.
