BESC 204 Exam 1 Questions and
Answers
Mycology - Answer-the study of fungi
Fungus - Answer-a eukaryotic, heterotrophic organism, devoid of chlorophyll, with chitin
in cell walls, that obtains its nutrients by absorption, usually reproduces by spores and
usually exhibits a pronounced polarization of growing cells
Eukaryotic - Answer-cell with a distinct nucleus
Prokaryotic - Answer-cell with no nucleus, genetic material is free-floating
Mycelium - Answer-collection of hyphae
Hyphae - Answer-collectively comprise mycelium, elongate tip growth/polarized growth
Saprotrophic - Answer-absorptive nutrition
Chitin - Answer-a structural polymer of glucose making up cell walls in fungi (in contrast
to plant cells with cellulose)
Septa - Answer-system for cell compartmentalization, cross walls that allow cytoplasm
and organelles to move through
Spores - Answer-reproductive propagules, usually microscopic
Woronin Bodies - Answer-plug up septa in case of damage to another cell, found in
ascomycetes
Meiosis - Answer-sexual reproduction
Mitosis - Answer-Asexual reproduction
Morphological Species Concept - Answer-organisms that look the same are of the same
species
Biological Species Concept - Answer-interbreeding natural populations mean they are
of the same species
Phylogenetic Species Concept - Answer-individuals of the same species share a
genealogical relationship
