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 different types of cells making up a colony of cyanobacteria.
A) Briefly describe the two different types of cells you can see in this image:
