Study Notes
Fungi Characteristics
- Cell wall made of chitin
- Eukaryotic
- Mostly multicellular, except for yeast which is unicellular
- Classified by how they reproduce
- Heterotrophs, obtaining nutrients by extracellular digestion
Fungi Structure
- Multicellular, composed of two main parts:
- Hyphae: fine filaments that make up the body of the fungi
- Mycelium: a branching network of hyphae growing together underground
Reproduction
- Most fungi alternate between sexual and asexual reproduction
- Two types of asexual reproduction:
- Spores: windblown reproductive cells produced by mitosis
- Fragmentation: pieces of hyphae break off and grow into new mycelia
- Sexual reproduction: used in unfavorable conditions, produces genetically diverse spores
- Sexual spore formation: two haploid hyphae of opposite types combine to form a diploid zygospore
Fungi Classification
- Four major groups of fungi, separated by reproductive factors:
- Zygomycota (bread mould)
- Basidiomycota (mushrooms)
- Ascomycota (truffles, powdery mildew, single-celled yeast)
- Imperfect fungi (cheese moulds, penicillin mould)
Fungi Functions
- Single most important function: helping to recycle nutrients
- Decomposers in the carbon and nitrogen cycles
