Learning objectives At the end of this lecture, you will be able to: 1) Draw a generalized prokaryotic cell. 2) Compare the sizes, complexities, and organelle compositions of prokaryotic and eukaryotic cells. 3) Draw and describe the location and function of major organelles within the eukaryotic cell.

Take out a piece of paper: 1) Draw a generalized cell. Add any structures/ features/organelles that you can think of that are found in a cell. If you’re unsure of where to begin, remember the 4 classes of biomolecules that we have discussed. Where are they found in the cell? What processes are they involved in? 2) Label your drawing. 3) If you’ve finished quickly, draw and compare different kinds of cells. How does a generalized bacterial cell compare to a generalized plant or animal cell?
