Study Notes

Classification of Fungi

Fungi include mushrooms, yeasts, and moulds, with around 144,000 identified species and an estimated 3.8 million total species.
Fungi were formerly classified with plants but share more cellular characteristics with animals, leading to their recognition as a separate kingdom.

Ecological Roles

Fungi are heterotrophs and cannot produce their own food; instead, they absorb nutrients from external sources.
They play a crucial role as decomposers, breaking down dead organic matter and recycling nutrients in ecosystems.
Certain fungi are capable of degrading plastic, presenting a potential solution to environmental plastic pollution.
Fungi establish symbiotic relationships, such as mycorrhizal associations with trees, where they exchange nutrients for sugars.

Contributions to Humanity

Essential in food production, fungi are used in the fermentation processes of bread, wine, and beer.
Penicillin, the antibiotic discovered by Alexander Fleming in 1928, originated from the mould Penicillium and has saved an estimated 200 million lives.

Dangers and Diseases

Some fungi can be harmful or lethal to humans, animals, and plants.
Historical impact includes potato blight, which caused famine in 19th-century Ireland, and Dutch elm disease, which has devastated millions of elm trees in the UK.

Overall Significance of Fungi

Fungi significantly influence ecosystems and human culture, underscoring the need for increased awareness and understanding of their diverse roles.
