What do cell theory and germ theory have in common?

Germ theory states that certain diseases are caused by the invasion of the body by microorganisms, organisms to small to be seen except through a microscope. The cell theory states that living things are composed of one or more cells, that the cell is the basic unit o life, and that cells arise from preexisting cells. The theories are similar because germ theory states that disease is caused by living organisms.

Hope this helps :)
