Diffusion, Osomosis And Active Transport

Question 1

Diffusion

Answer 1

Net movement of particles from an area of higher concentration to an area of lower concentration

Question 2

Osmosis

Answer 2

Net movement of water molecules across a partially permeable membrane from a region of higher water concentration to an area of lower concentration

Question 3

Active Transport

Answer 3

Movement of particles across a membrane against a concentration gradient (area of lower concentration to a higher conc) using energy transferred during respiration.
