Textbook Question
Chapter 25, Problem 4AL
Analysis of sclerotia and conidia formation in the filamentous ascomycete Aspergillus flavus suggests that formation of these structures is cell density dependent. Specifically, high cell density cultures yield conidia, whereas low cell density triggers sclerotia formation. Review the structure and function of conidia and sclerotia, and formulate a hypothesis to explain why their development would be regulated in a density-dependent manner. List several specific testable predictions based on your hypothesis.
Read the original paper: Horowitz-Brown, S., et al. 2008. Morphological transitions governed by density dependence and lipooxygenase activity in Aspergillus flavus. Appl. Environ. Microbiol. 74:5674.

Relate plasmogamy and karyogamy to the process of fertilization and describe whey we need to separate these two things in the life cycle of the fungi.
Differentiate between the monokaryotic and dikaryotic conditions.
Compare and contrast an animal life cycle with that of a typical mushroom including the haplophase, dikaryophase, and diplophase, products of meiosis, plasmogamy, and karyogamy.
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…

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. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges.
