Two petri dishes containing a medium were obtained. The petri dishes were labeled and divided into four quadrants. The control plate, labeled control, contained regular growth medium and the experimental plate, labeled NH4NO3, contained 1% ammonium nitrate. Using a sterile pipette, three drops of the C-Fern spore culture were added into each petri dish and spread across the surface of the medium with a sterile, disposable inoculating loop. After the spores were observed under a dissecting microscope, the petri dishes were placed under the plant lights, where they were stored for five weeks. During the fifth week, the number of spores germinated was counted and recorded after viewing each petri dish under a microscope. The class data from lab
