In this lesson our instructor does a laboratory review for each topic covered so far in our AP biology courses. First she discusses diffusion, osmosis, water potential, enzyme catalysis, mitosis, meiosis, plant pigments and photosynthesis lab. Then she talks about cell respiration, molecular biology, genetics of organisms, and the Chi-square analysis. She also lectures on population genetics, evolution, transpiration, physiology of the circulatory system, temperature, metabolism in ectotherms, and animal behavior. Lastly, she goes over dissolved oxygen and aquatic primary productivity. Four complete example videos round up this lesson.
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
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.
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.
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.
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.
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
Dissolved Oxygen and Aquatic Primary Productivity. Use changes in
dissolved oxygen to determine primary productivity.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
