Fungi: General Characteristics
Fungi versus fungi
• “fungus” is used inclusively for a
heterogenous group of organisms that
have traditionally been studied by
mycologists
• “Fungi” refers to the organisms in the
Kingdom Fungi, the true fungi, also
called the “Eumycota”
Are fungi bacteria?
• NO
• Eukaryotic
• Different cell wall
– Glucans, chitin, other polysaccharides
– As opposed to peptidoglycan
Fungi: General Characteristics
• Not plants – why?
– No chlorophyll
– No leaves, stems, roots
– Primary carbohydrate storage as glycogen
– Cell wall composition (not cellulose)
• (Language from botany)
Fungi: General Characteristics
• Not animals – why?
– Absorptive nutrition
– (unicellular)
– Non-motile
Fungi: General Characteristics
• Eukaryotic
• Heterotrophic
– Absorptive nutrition
– Need free water to move nutrients
– Some omnivorous, other more restricted
• Diversity of growth conditions
• Reproduction:
– Asexual & sexual
– Via spores
Fungi: General Characteristics
•
•
•
•
Filamentous or unicellular (yeasts)
Definite cell walls
Nonmotile (some motile reproductive cells)
Most saprobes
– Some parasites
– Some predacious
