Cell Structure


Objectives:


Before you leave at the end of the laboratory period you should know the parts of a microscope and how to determine total magnification. You should be able to recognize the organelles in a plant and an animal cell, and recall the functions of each. You should also know the stains that you used and what they stained.

Introduction:

As 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. Your textbook is an excellent reference, so you may want to refer to it during this exercise.
