ScienceCellsGCSEAQA Created by: BenBaiton15Created on: 11-05-19 18:14 What is diffusion? the net movement of particles from an area of higher concentration until they are evenly spread. 1 of 8 Give an example of where diffusion occurs in the lungs Oxygen and carbon dioxide diffuse during gas exchange in the lungs. 2 of 8 What are the 3 factors that affect diffusion? The difference in concentration (concentration gradient), the temperature and the surface area of the membrane. 3 of 8 What is osmosis? the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane. 4 of 8 What is active transport? the movement of substances against a concentration gradient from an area of low concentration to high concentration 5 of 8 Which of these three doesn't move against a concentration gradient: Osmosis, Active Transport, Diffusion? Active Transport 6 of 8 Which of these ALWAYS involves the movement of water: Osmosis, Diffusion, Active Transport? Osmosis 7 of 8 Which of these requires energy from respiration: Osmosis, Diffusion, Active Transport? Active Transport 8 of 8
