Laboratory Review

  • Lab 1: Diffusion and Osmosis. Study the movement of substances across a semipermeable membrane. Observe plasmolysis in a plant cell.
  • Lab 2: Enzyme catalysis. Determine the rate of conversion of H2O2 to H2O and O2 with and without the enzyme catalase. Determine the effect of boiling and acid on enzyme activity.
  • Lab 3: Mitosis and Meiosis. Determine the percentage of time a cell spends in each stage of mitosis. Use models of chromosomes to develop an understanding of the stages of meiosis.
  • Lab 4: Plant Pigments and Photosynthesis: Use paper chromatography to separate plant pigments. Measure the rate of photosynthesis for various plant pigments.
  • Lab 5: Cell respiration. Determine the rate of oxygen consumption in dry and germinating seeds through the use of a respirometer. Study the effect of temperature on cell respiration.
  • Lab 6: Molecular Biology. Transform E. coli with a plasmid carrying genes for antibiotic resistance. Digest phage DNA with restriction enzymes and separate the fragments through gel electrophoresis.
  • Lab 7: Genetics of Organism. Determine the mode of inheritance of certain traits in Drosophila melanogaster by conducting breeding experiments. Do a chi-square analysis on the results.
  • Lab 8: Population Genetics and Evolution. Determine how many individuals in your class can and cannot taste PTC. Use the Hardy-Weinberg equation to analyze the results.
  • Lab 9: Transpiration. Use a potometer to study the rate of transpiration under various conditions. Observe and identify different tissue and cell types in a plant stem.
  • Lab 10: Physiology of the Circulatory System. Use a sphygmomanometer to measure blood pressure. Observe the baroreceptor reflex by assessing change in pulse rate immediately after standing up. Study the effect of temperature on heart rate in an ectotherm.
  • Lab 11: Animal Behavior. Observe the movement of pill bugs with access to a wet and dry environment. Observe mating behavior in fruit flies.
  • Lab 12: Dissolved Oxygen and Aquatic Primary Productivity. Use changes in dissolved oxygen to determine primary productivity.
