Chapter 6: A Tour of the Cell What are the 3 main tenets of cell theory? What are the major lines of evidence that all presently living cells have a common origin? What is surface area to volume ratio, and why is it an important consideration for cells? What (usually) happens to surface area to volume ratio as cells grow larger? Compare and contrast: LM and EM SEM and TEM Include the terms resolution and magnification in your discussions. Describe cell fractionation. Why is it done, and how is it done? Include the terms lyse, centrifugation, pellet, and supernatant in your discussion. How do prokaryotic cells and eukaryotic cells differ from each other in typical size and general organization? Describe cytoplasm, cytosol, nucleoplasm, and the general role of membranes in cells. List as many organelles as you can think of. Describe their structures and key functions. Draw and label a typical animal cell and a typical plant cell, including organelles. Describe the nuclear envelope, nuclear pores, chromatin, chromosomes, and nucleoli in terms of structures and key functions. Name something that you KNOW must get out of the nucleus for cells to function.
