1.) to learn to use a compound microscope properly
2.) to review the main parts of a cell, using your textbook as a referenceAs you will find in this course, there is no such thing as a "typical" cell. During this period you will look at four "representative" eukaryotic cells: two plant cells (one with chloroplasts that are easy to focus on, and one without chloroplasts that will be more challenging), one animal cell, and one example of a single-celled organism. In each case you will try to locate as many organelles as you can. You will also examine a prepared slide of some prokaryotic bacterial cells.
