Characteristics of Kingdom Fungi
📌 Fungi are eukaryotic organisms possessing cell walls but lacking chlorophyll, meaning they cannot produce their own food (they are heterotrophic).
🍄 Fungal body structures include diverse shapes (oval, thread-like, mushroom cap) and can be unicellular or multicellular.
🔬 The body structure consists of hyphae (vegetative for absorption, generative for reproduction/spore production), with branching hyphae forming a mycelium.
🧱 Fungal cell walls are reinforced by chitin (substance similar to that in arthropod exoskeletons).

Modes of Nutrition in Fungi
🌱 Saprofitic fungi absorb organic matter from dead organisms or materials (like bread), acting as decomposers in the ecosystem.
🦠 Parasitic fungi obtain organic matter from living organisms (hosts), often known as pathogenic fungi causing diseases.
🤝 Mutualistic fungi share nutrients with living organisms, such as in the symbiosis with blue-green algae forming lichen (lumut kerak).

Reproduction in Fungi
🧬 Fungi reproduce both vegetatively (asexually), through budding (unicellular) or hyphal fragmentation, and sexually (generatively) via syngamy (plasmogamy and karyogamy).
♀️ Sexual reproduction involves the fusion of hyphae, leading to the formation of sexual spores like zygospore, ascospore, and basidiospore.
📊 Sexual reproduction methods are used to classify fungi into four main divisions: Zygomycota, Ascomycota, Basidiomycota, and Deuteromycota.

Fungal Divisions and Examples
🔱 Zygomycota: Produce thick-walled zygospores; hyphae are non-septate (coenocytic). Examples include *Rhizopus stolonifer* (bread mold) and *Rhizopus oryzae* (tempeh fungus).
🍂 Ascomycota: Have septate hyphae and produce ascospores (usually 8 per ascus) within a sac called an ascus. Includes *Saccharomyces cerevisiae* (yeast for bread/tapai) and *Penicillium notatum* (antibiotic producer).
🍄 Basidiomycota: Are generally macroscopic, multicellular fungi with septate hyphae; they form basidiospores on a club-shaped structure called a basidium. Examples include edible mushrooms like *Volvariella volvacea* and pathogenic fungi like *Puccinia arachidis* (parasite on peanuts).
❓ Deuteromycota (Fungi Imperfecti): Characterized by septate hyphae and reproduce only asexually (sexual reproduction method unknown). Often saprophytic or parasitic, causing diseases like ringworm (*Trichophyton*).

Key Points & Insights
➡️ Fungi are distinctly not plants because they lack chlorophyll and must obtain nutrition heterotrophically.
➡️ The structure of fungal hyphae can be septate (with cross-walls) or non-septate (coenocytic), which helps distinguish divisions (e.g., Zygomycota are non-septate).
➡️ Ascomycota form spores in an ascus, while Basidiomycota form spores on a basidium within the basidiocarp (fruiting body).
➡️ Deuteromycota are historically categorized as "imperfect fungi" because their sexual reproductive cycle has not been observed.
