Characteristics of Fungi
Eukaryotic organism
Non-photosynthetic

Heterotrophs
Cell Wall: Chitin

Characteristics of Yeast
Unicellular
simplest form of fungi
budding cells: reproduction
Pseudohyphae
Capsule: negative stain (India ink)
Oval/Spherical
Exist in yeast & mold form
Dimorphic form
Temp for mold
Room temp
Temp for Yeast
Body temp
Characteristics of Molds
Multicellular
Develop tiny spores that ride in the air & spread by air currents
Prefer neutral ph
Hyphae: ribbon-like structure
Septae
Mycelium: intertwined mass
Spores
Reproduction of Filamentous fungi
Asexually by fragmentation of their hyphae
Asexually & Sexually by formation of spores
Unicellular or multicellular spore that is not enclosed in a sac
Conidiospore
Conidia formed by fragmentation of septate hypha into single thickened cell
Arthroconidia
Conidia formed by fragmentation of septate hypha into single thickened cell
Arthroconidia
Formed in a sporangium or sac
Sporangiospore
Formed by hypha of one organism
Asexual spores
The fusion of nuclei from two opposite mating strains of same specie
Sexual spores
Disease caused by fungal infections
Mycosis
Mycoses are classified into groups according to:
Degree of tissue involvement
Mode of entry to the host
