Fungi - Classification (Morphology) Flashcards
Fungi domain
Eukaryotic
Fungal cell membrane made of
Ergosterol
Unicellular/multicellular
Both
Asexual/sexual
Both
Chlorophyll present
None
Yeast reproduction
Forms buds that eventually detach from original cell
Yeast spp
Cryptococcus neoformans Saccharomyces cerevisiae (makes bread,wine)
Yeast like reproduction
Bud remains attached to mother cell and buds to form chains with pseudohyphae (not true hyphae-those are in moulds, no presence of budding)
Yeast like spp
Candida
Mould growth pattern
Grow as long branching filaments called hyphae
Hyphae types
Septate (segmented)
Aseptate (no segments)
Moulds hyphae grow continuously to form a tangled mass called
Mycelium
Types of mycelium
Aerial - non-motile asexual spore that projects outwards the surface into the air - called conidia
Vegetative - part of mycelium that penetrates culture medium - anchors mould
Aerial hyphae location
Produced on tip of hyphae/spore producing conidiophores
Aerial hyphae development
Spores detach when mature
Small conidium (spore)
Microconidia
Large conidium (spore)
Macroconidia
Conidia enclosed in sac (sporangium)
Endospores
Moulds reproduce by
Forming either sexual or asexual spores
Mould spp
Dermatophytes, Aspergillus
Pencillium, Rhizopus, Mucor
Thermally dimorphic
Inside humans - become yeast
Outside - become moulds
Dimorphic fungi spp
Histoplasma capsulatum Blastomyces dermatitidis Coccidioides immitis Paracoccidioides brasiliensis Penicillium marneffei Sporothrix schenckii Emmonsia spp
