Observing Bacteria in Colonies In fresh or saltwater habitats, cyanobacteria will appear (without a microscope) as very small green lines (as can be seen in this video). Observe the following images of cyanobacteria colonies under 100x and 400x magnification with a light microscope: Anabaena sp. 100x magnification Anabaena sp. 400x magnification As you can see, cyanobacteria grow as two different types of cells: those that are photosynthetic (fixing carbon dioxide to make sugars), and heterocysts (that fix nitrogen to make proteins and nucleic acids). Although these cells are genetically identical, each is able to accomplish this via differences in gene expression, a key concept in biology you will continue exploring this quarter. In the 400x magnification image, you should be able to clearly see two…
