Diffusion, osmosis and active transport

Question 1

Diffusion

Answer 1

Movement of particles from an area of high concentration to low concentration

Question 2

Osmosis

Answer 2

The movement of water from an area of high water potential to one with low water potential through a partially membrane

Question 3

Active transport

Answer 3

Movement of particles from an area with low concentration to one with high concentration (up a concentration gradient) therefore it requires energy
