In the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions:
Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments.
Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments.
Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments.
Non-filamentous cyanobacteria generally produce spores…

anana are able to regenerate after they are cut in half. Answer the three questions to explain how planaria
grow, heal and regenerate themselves at each of the scales: Organism, Cellular, and Molecular.
Three scales:
Use the space below to show what happened at each of the 3 scales
Organism Scale:

observable trait?
right after cut
-> after a few days--------------> after 2 weeks
Cellular Scale:
What is going on
inside the cell(s)
to produce the
observable trait?
Name the process that results in more cells:
right after cut --------------->
after a few days -----------------> after 2 weeks
Molecular Scale: Name of the process that happened to DNA before cells divided:

Which statement about life cycles with a dikaryon stage is false?
A zygosporangium results from the fusion of two coenocytic hyphae.
In effect, the dikaryon is neither diploid nor haploid.
Dikaryotic hyphae often have characteristics that are different from those of their n or 2n products.
The only true diploid structure is the zygote.
There are no gamete cells, only gamete nuclei.

If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again.
