Dinoflagellate Pyrocystis Osmosis Experiment

Satisfactory Essays
For this experiment, the researcher built upon prior knowledge from past experiments. The researcher had observed bioluminescent and fluorescent organisms in their natural habitat. The researcher then wondered how the altering of the dinoflagellate circadian rhythm would affect the brightness and duration of their glow. The researcher then created the following hypothesis, “If the dinoflagellate Pyrocystis lunula is taken off of its 12/12 light/dark cycle circadian rhythm and subjected to 18/6 and 6/18 hour light/dark cycles then the duration and intensity of its bioluminescence will decrease.” In order to test the hypothesis, the researcher obtained the Pyrocystis lunula and separated them into three different jars. The researcher then placed
