Study Notes
Fungi General Characteristics
- Fungi are heterotrophs, meaning they require organic carbon.
- They are saprotrophs, decomposing dead organic matter.
- Fungi form symbiotic relationships with other species, such as algae and bacteria.
- Fungi serve as food sources and play a role in food production for humans and other organisms.
- Fungi have cell walls made of chitin.
- Fungi can be multicellular (e.g., molds) or unicellular (e.g., yeast).
- Fungi have hyphae, long, branching, cellular structures.
- Hyphae can form a network called a mycelium.
- Vegetative hyphae grow along the substrate.
- Reproductive hyphae extend upwards and produce spores.
- Fungi exhibit thermal dimorphism: molds grow at room temperature, while yeast grows at 37°C.
- Some fungi are opportunistic pathogens, infecting weakened or immunocompromised individuals.
Types of Fungi
Zygomycetes
- Zygomycetes produce zygospores during sexual reproduction and sporangiospores during asexual reproduction.
- Rhizopus stolonifer is an example of a zygomycete, producing both zygospores and sporangiospores.
Ascomycetes
- Ascomycetes form ascospores during sexual reproduction and conidiospores during asexual reproduction.
- Penicillium notatum and Aspergillus niger are examples of ascomycetes, producing conidiospores.
Basidiomycetes
- Basidiomycetes produce basidiospores during sexual reproduction.
- They generally lack well-defined asexual reproduction.
Yeast
- Saccharomyces cerevisiae (budding yeast) is a type of yeast.
