Cells II includes three experiments ideal for supporting the topics of cellular transport, energy storage, and photosynthesis and respiration. First, cellular osmosis and diffusion are modeled to introduce methods of cellular transport: passive transport, active transport, facilitated diffusion, pinocytosis, and phagocytosis. Second, students learn how plant and animal cells obtain and store chemical energy and how energy is released during cellular respiration and stored as ATP. Then, they compare the energy content of carbohydrates, lipids, and proteins using calorimetry. Third, students compare the processes of anaerobic and aerobic respiration and learn about the organisms in which each occurs. Students separate plant pigments using paper chromatography to support the study of photosynthesis. Allow 90 - 120 minutes lab time. Designed for 24 students working in groups of four. Requires thermometers, beaker, test tubes, test tube support, goggles, scissors, colored pencils, matches, and food samples for calorimetry.
