A. Passive Transport Movement of molecules from areas of high concentration (crowded) to low concentration (less crowded) where no energy is required *Note: molecules will keep moving even after equilibrium is reached Three types of passive transport: Simple diffusion Osmosis Facilitated diffusion
B. Simple Diffusion Random movement of molecules from high concentration to low concentration Ex: spraying perfume, drop food coloring in water
C. Osmosis Movement of WATER molecules (fast and small) across a selectively permeable membrane from areas of high concentration to low concentration
D. Facilitated Diffusion Movement of molecules from areas of high to low concentration with the help of proteins
