During an experiment, filamentous green algae were illuminated with light along a spectrum of different wavelengths. Aerobic bacteria were added and he noticed that the bacteria congregated in certain regions along the spectrum where red and blue light was found. What can you conclude about the congregation of bacteria in the red and blue areas? a. bacteria congregated in these areas due to the increased amount of oxygen release b. bacteria release excess carbon dioxide in these areas c. bacteria are attracted to red and blue light d. bacteria congregated in these areas due to an increase in the temperature of red and blue light

The cyanobacteria, also known as blue-green algae, are a diverse group of photosynthetic bacteria. Their thylakoid membranes contain chlorophyll a, similar to plants. In addition to storing photosynthate as glycogen, cyanobacteria also store nitrogen. Some cyanobacteria can fix nitrogen in specialized cells called heterocysts. The major pigments found in cyanobacteria include phycocyanin and phycoerythrin. These pigmented structures are associated with photosystems, and the light energy captured by these pigments is used for carbon fixation in internal structures. Other specialized cells in cyanobacteria include reproductive resting cells called akinetes and motile reproductive filaments called hormogonia.
