Hypothesis:
Strain B does not respond to the signal.
Methods:
The variables in the experiment were: the strain type (independent variable) and the percent light bulbs (dependent variable). We had seven plates: two with the A filtrate on the B strain, two with B filtrate on the B strain, one with distilled water on the A strain, and two with A filtrate on the A strain. The petri dishes were labeled and incubated for two weeks. Then the petri dishes were retrieved and a light microscope was used to count the number of male and female gametophytes that were produced in each dish. The male gametophytes were the light bulbs and the female/hermaphroditic gametophytes mittens. The data collected was then placed into a table and compared.
