Ch.12: The Eukaryotes: Fungi, Algae, Protozoa, and Helminths Flashcards
Characteristic of Fungi: kingdom, nutrition type, multicellurity, cellular arrangement, food acquisition method, characteristic features
Fungi chemoheterotroph all, except yeast unicellular, filamentous, fleshy absorptive sexual and asexual spores
The study of fungi
mycology
Difference between bacteria and fungi
plasma membrane: ergosterols cell wall : chitin Eukaryotic asexual/sexual spores heterotrophic, aerobic, faculatative
The _______ of a mold or fleshy fungus consist of long filaments of cells joined together; filaments are called HYPHAE
thallus
a mass of hyphae
mycelium
______ are nonfilamentous, unicellular fungi that are typically spherical or oval. frequently found as a white powdery covering on fruits and leaves. capable of facultative anaerobic growth.
yeast
________ ______ such as Saccharomyces divide unevenly.
budding yeast
_______ _______ such as Schizosaccharomyces divide evenly to produce two new cells.
Fission yeast
Some fungi most notably the pathogenic species exhibit _________- two forms of growth, they can either grow as a mold or as a yeast.
dimorphism
Dimorphism in pathogenic fungi is temperature-dependent at
37 degrees celcius (yeast)
25 degrees celcius (mold)
True or False: Although fungal spores can survive for extended periods in dry or hot environments, most do not exhibit the extreme tolerance and longevity of bacterial endospores
True
_______ ______ are formed by hyphae of one organism. Genetically identical to the parent.
Asexual Spores
_________ ______: result from the fusion of nuclei from two opposite mating strains of the same species of fungus. will contain both parental strains.
sexual spores
Benefits of Fungi
decomposition nutrient cycling
yeast
antibiotics
increases surface area for nutrient absorption
Characteristic of Algae: kingdom, nutrition type, multicellurity, cellular arrangement, food acquisition method, characteristic features
domain eukarya; DIVIDED INTO SUPERGROUPS photoautotrophs both multi/uni unicellular, colonial filamentous, tissues diffusion pigments
