Osmosis Passive 4. Active transport Active 5. Pinocytosis/phagocytosis/exocytosis Active 2. Which mechanism: a.) uses no energy and results in an even distribution of molecules? Diffusion b) uses no energy, and occurs across a semi-permeable membrane? Osmosis c) occurs across the membrane of red blood cells causing them to swell and burst when placed in distilled water? Osmosis d) uses energy and allows the cell to take into itself particles and bacteria? Phagocytosis e) moves substances across the plasma membrane from a low to a high concentration?
