Fungi: Molds, Yeasts, Mushrooms, and Lichens Worksheet
Directions: Complete the tables and questions below. The textbook and Internet resources may be used to identify organisms
and answer the questions. Include all applicable group identification classifications (e.g., Linnaean or phylogenetic classification).
When classifying the fungi slides, use the following categories: Chytridiomycota, Zygomycota, Glomeromycota, Ascomycota, or
Basidiomycota. Drawings of the organisms are required, while pictures of the organisms are optional. Pictures of the slides
may be helpful when studying for the lab practical. Characteristics include unique or prominent features (e.g., life cycle,
reproduction, structural features, or nutritional highlights). Add any information that will be helpful for study. Two or three
students may work together; however each student must provide answers in his or her own words. All references should be
included at the end of the assignment in GCU style.

Microorganism Observation Questions
Directions: Thoroughly answer the questions below in complete sentences. Any use of outside resources should have
in-text citations and be listed at the end of the assignment in GCU style, and original wording is expected for all answers.
Failure to follow these directions can be considered plagiarism or cheating that can result in point deductions and referral
for Code of Conduct violations.
1. Explain plasmogamy. Is this part of fungal asexual or sexual reproduction?
Plasmogamy is part of sexual reproduction, in which it is the union of two cytoplasms of two parent mycelia.
2. Explain dikaryon. Is this part of fungal asexual or sexual reproduction?
Dikaryon, which means two nuclei, is when there are pairs of haploid nuclei are paired in one cell from each parent.
3. Explain karyogamy. Is this part of fungal asexual or sexual reproduction?
Karyogamy, is the next step that comes after plasmogamy in sexual reproduction. During this stage, the two haploid nuclei
from each pair fuse together which produces diploid cells.
4. Explain why pheromones are important in fungi sexual reproduction. Be specific in your response.
Pheromones are very important because they are basically the trigger for sexual reproduction. Without
pheromones, the two hyphae wouldn’t release these signaling molecules with therefore would prevent two
mycelia from reproducing.
