Lab 4: Histology

Question:
How do the different types of tissue in the body differ from one another?

Hypothesis:
I think that each type of tissue will have significant differences in structure and its own unique qualities compared to other tissue types. If the tissues are compared to one another, then they will each have their own unique qualities and differences in structure. I believe this because each type of tissue has a different function. With cells, the structure reflects its function. I believe this rule will apply to tissues as well since tissues are made up of cells.

Materials:
Parts of the Microscope Simulator (http://www.udel.edu/biology/ketcham/microscope/scope.html)
Virtual Compound Microscope Simulator (http://www.udel.edu/biology/ketcham/microscope/scope.html) http://www.histology-world.com/ http://www.bu.edu/histology/m/index.htm
