Fungi Characteristics and Types

Characteristics of Fungi

• Eukaryotic organisms
• Heterotrophic, obtaining nutrients by decomposing organic matter or forming symbiotic relationships with other organisms
• Non-motile, except for a few species that use flagella
• Cell walls composed of chitin, a polysaccharide

Types of Fungi

• Mold: multicellular, filamentous fungi that grow on surfaces
• Yeast: unicellular fungi that reproduce by budding
• Mushrooms: fruiting bodies of fungi that produce spores
• Lichens: symbiotic relationships between fungi and algae or cyanobacteria

Fungal Nutrition

• Saprotrophic: obtain nutrients by breaking down dead organic matter
• Parasitic: obtain nutrients by infecting and harming other organisms
• Mutualistic: form symbiotic relationships with other organisms, such as mycorrhizal fungi with plant roots

Fungal Reproduction

• Asexual reproduction: produce spores through mitosis
• Sexual reproduction: produce spores through meiosis and fusion of gametes
• Heterothallism: some fungi require two compatible partners to produce fertile offspring

Ecological Roles of Fungi

• Decomposers: break down organic matter, recycling nutrients
• Symbionts: form relationships with plants, improving nutrient uptake
• Pathogens: cause disease in plants and animals
• Food sources: edible mushrooms and other fungi are a food source for humans and other animals

Fungal Reproduction

• Asexual reproduction in fungi involves producing spores through mitosis.
• Sexual reproduction in fungi involves producing spores through meiosis and the fusion of gametes.
• Heterothallism in fungi requires two compatible partners to produce fertile offspring.

Ecological Roles of Fungi

• Fungi act as decomposers, breaking down organic matter and recycling nutrients.
• Fungi form symbiotic relationships with plants, improving nutrient uptake.
• Fungi can be pathogens, causing disease in plants and animals.
• Fungi can be a food source, with edible mushrooms and other fungi being consumed by humans and other animals.
