|
Mycology
|
Study of fungi
|
|
|
Thallus
|
Vegetative structure of fungi, lichens, or algae
|
|
|
Hyphae
|
Long, filamentous cells in fungi
|
|
|
Mycelium
|
Mass of hyphae, branched and intertwined (typical of molds)
|
|
|
Yeast
|
Non-filamentous, unicellular fungi
|
|
|
Fission yeasts
|
divide symmetrically
|
|
|
Budding yeasts
|
divide asymmetrically
|
|
|
Dimorphic Fungi
|
Yeastlike at 37°C and moldlike at 25°C
|
|
|
Pseudohyphae
|
Buds that do not separate from the mother cell
|
|
|
Fungi Reproduction
|
Sexual (main method) and asexual through the formation of spores
|
|
|
Asexual spores
|
Formed by the hyphae, and become genetically identical to the parent after germination
|
|
|
Sexual spores
|
Fusion of nuclei from two opposite mating strains
|
|
|
Two types of asexual spores
|
Conidiospore
Sproangiospore |
|
|
Conidiospore (conidia)
|
Not enclosed in a sac, produced in a chain at the end of a conidiophore
|
|
|
3 types of Conidia
|
Arthroconidia
Blastoconidia Chlamydoconidia |
|
|
Arthroconidia
|
formed by the fragmentation of a septate hypha into single thickened cells
|
|
|
Blastoconidia
|
buds come off of the parent cell
|
|
|
Chlamydoconidium
|
Thick-walled spore formed by rounding and enlargement within hyphae
|
|
|
Sporangiospore
|
Formed withing sporangium (sac), at the end of an areal hypha (a sporangiophore)
|
|
|
3 Phases of Sexual Reproduction
|
Plasmogamy
Karyogamy Meiosis |
|
|
Plasogamy
|
Haploid nucleus of donor cell (+) penetrates recipient's cytoplasm (-)
|
|
|
Karyogamy
|
(+) and (-) nuclei fuse to form diploid zygote nucleus
|
|
|
Meiosis
|
Diploid nucleus --> Haploid nuclei
|
|
|
Fungi Adaptations
|
-Grow in acidic, dryer, aerobic environments
-metabolize complex carbohydrates |
|
|
Sexual Spores
|
-Zygospore
-Ascospore -Basidiospore |
|
|
Ascospore
|
formed in a sac
|
|
|
Zygospore
|
spore in a thick wall, formed by fusion of haploid cells
|
|
|
Basidiospore
|
Formed on a pedestal
|
|
|
Rhizopus Life Cycle
|
Zygomycete
|
|
|
Talaromyces Life Cycle
|
Ascomycete
|
|
|
Life Cycle Basidiomycete
|
Basidiomycete
|
|
|
Teleomorphic Fungi
|
Produce sexual and asexual spores
|
|
|
Anamorphic Fungi
|
Produce asexual spores only
|
