Study Notes
Kingdom Fungi
- Fungi are a diverse group characterized by multicellular structure and cell walls.
- Fungi are heterotrophic, meaning they obtain nutrients by absorbing them from their surroundings. This can take the form of saprophytic (decomposers) nutrition, parasitic nutrition, or symbiotic relationships.
- Fungi have hyphae (filaments), which can be septate (with cross-walls) or aseptate (without cross-walls).
- Hyphae form a network called mycelium.
- Some fungi possess haustoria, specialized hyphae used to penetrate host tissue.
- Fungi reproduce sexually and asexually, both resulting in spore formation. The formation of spores from both sexual and asexual cycles are crucial for fungal reproduction.
- Fungi have diverse metabolic activities, playing roles as decomposers, parasites, and mutualists.
Fungal Divisions
- Zygomycota, Ascomycota, and Basidiomycota are three major divisions of fungi.
- Zygomycetes are fast-growing molds, parasites, and commensal symbionts. Reproduction includes a sporangium (holder of asexual spores) and a zygosporangium (contains a zygospore - sexual spore).
- Ascomycetes are a diverse group that includes marine, freshwater, and terrestrial species. Asexual reproduction occurs via specialized structures called conidiophores that produce conidia (asexual spores). The sexual reproductive structures are called ascocarps, which contain ascospores (within asci).
- Basidiomycota are characterized by mushrooms, puffballs, and shelf fungi. They reproduce only sexually in a structure called a basidiocarp. Basidia are club-like structures that hold basidiospores.
Lichens
- Lichens are a symbiotic partnership between fungi (usually ascomycetes) and algae or cyanobacteria.
- Lichens have three main growth forms: foliose (leaf-like), fruticose (shrub-like), and crustose (encrusting).
- Lichens are important pioneer organisms, aiding in soil formation on bare rock.
