Fungi

Kingdom Fungi

Composed of unicellular and multicellular eukaryotes, closely related to animals and characterized by their heterotrophic nature.

Chitin

A structural component found in fungal cell walls, distinct from cellulose found in plant cell walls.

Heterotrophs

Organisms that cannot synthesize their own food and must obtain nutrition from external sources.

Saprotrophic fungi

Fungi that decompose non-living organic materials and play a vital role in recycling nutrients.

Mycelium

An interconnected network of hyphae that forms the vegetative structure of fungi.

Hyphae

Long, branching filaments that make up the body of fungi.

Fungal spores

Haploid cells produced for reproduction, which disperse and develop into mature fungi.

Basidiomycota

A phylum of fungi that includes many edible mushrooms and is characterized by basidia, the spore-forming structure.

Ascomycota

The largest phylum of fungi, including yeast and Penicillium, characterized by the formation of asci during sexual reproduction.

Zygomycota

A former phylum of fungi, now mostly classified as Mucoromycota or Zoopagomycota, primarily known for asexual reproduction.

Mycorrhizae

Symbiotic associations between fungi and plant roots that enhance nutrient absorption.

Lichen

Complex life forms arising from the symbiotic relationship between fungi and algae or cyanobacteria.

Fungal reproduction

Occurs through asexual or sexual means, typically involving the production of spores.

Decomposers

Organisms such as fungi that break down dead organic matter, returning nutrients to the soil.

Fungi cell structure

Fungi have eukaryotic cells with cell walls made of chitin, unlike plants which have cellulose.

Parasitic fungi

Fungi that obtain nutrients from a living host, often harming the host in the process.

Environmental roles of fungi

Fungi play key roles in ecosystems as decomposers, recyclers, and symbiotic partners.

Fungal pathogens

Fungi that can cause diseases in plants and animals, impacting health and agriculture.

Fungal nutrition

Fungi obtain nutrients through absorption, breaking down organic matter externally before absorbing the smaller molecules.

Fungal lifecycle

Fungi have complex lifecycles that include both sexual and asexual reproduction stages, with spore dispersal being key.

Ambrosia fungi

Fungi that live in symbiosis with wood-boring beetles and help in digesting wood.

Yeast

Single-celled fungi, often used in baking and brewing, capable of fermentation.

Fungal enzymes

Enzymes produced by fungi that break down complex organic substances into simpler molecules.

Endophytes

Fungi that live within plant tissues without causing harm, often providing benefits like enhanced growth.

Fungal bioremediation

The use of fungi to degrade environmental contaminants, aiding in the cleanup of polluted sites.
