SOMEONE PLEASE HELP NE ITS DUE TODAY!!!
In 1882, Theodor W. Engelmann carried out an experiment using filamentous green algae, oxygen-requiring bacteria, a light source, and a prism. He placed the algae and bacteria together in liquid medium in a glass tank. Then he placed the prism next to the tank and the light source a bit farther away. When he directed the light onto the prism, it dispersed into its component wavelengths as shown in the diagram. He found that if one filamentous alga lined up along the distribution of wavelengths of light coming into the tank, the bacteria tended to congregate in specific areas around the algal cell. These areas correlated to the wavelengths of light striking the algal cell. Pose a scientific question that Engelmann might have asked about an algal cell after making his observations from this experiment.
