Study Notes
Definition and Classification of Fungi
- Fungi belong to the Kingdom Fungi, which is part of the domain Eukarya and is distinct from animals, plants, and protists.
- Over a million fungal species are estimated to exist, but fewer than 100,000 have been documented.
Key Characteristics of Fungi
- Fungi can be multicellular or unicellular; single-celled forms are referred to as yeasts.
- The majority of the fungal life cycle is spent in a haploid state, with diploid cells formed during sexual reproduction.
- Fungal cell walls are composed of chitin, a tough carbohydrate, unlike the cellulose found in plant cell walls.
Habitat and Ecological Role
- Fungi thrive globally in diverse habitats including deserts, with most preferring terrestrial environments.
- Many fungi decompose organic matter in soil and dead material, playing a vital role as primary decomposers in ecosystems.
- Fungi interact with plants and animals, forming symbiotic relationships that benefit both parties.
Nutrient Transport and Efficiency
- Fungi utilize unique fluid networks to transport nutrients and nuclei, similar to transportation systems, enhancing movement efficiency.
- This system prevents microscopic traffic congestion, allowing effective nutrient management within fungal structures.
Common Examples of Fungi
- Familiar types of fungi include molds, mushrooms (e.g., yellow staghorn and jelly ears), and yeasts, as well as specific molds like blue turkeytail.
