    Study Notes

    Fungal Structure

    • Hyphae are long, branching filaments that make up the body of the fungus, allowing it to absorb nutrients from its surroundings.
    • Mycelium is the mass of interconnected hyphae that makes up the body of the fungus, and can grow large and spread out to search for nutrients.
    • Spores are the reproductive structures of the fungus, produced at the tips of specialized hyphae called sporangiophores, and are released into the air or water to begin a new fungal colony.
    • The cell wall of fungi is made up of chitin, a tough, flexible polysaccharide that provides structural support and protection.
    • Fungal cells contain various organelles, including nucleus, mitochondria, ribosomes, and endoplasmic reticulum, involved in cellular functions such as metabolism, energy production, and protein synthesis.
    • Some fungi produce elaborate reproductive structures, visible to the naked eye, used to identify different species of fungi.

    Benefits of Fungi

    • Fungi are important decomposers, breaking down dead organic matter such as leaves, wood, and animal carcasses, and recycling nutrients back into the ecosystem.
    • Fungi help maintain soil fertility and nutrient cycling in forests, grasslands, and other ecosystems.
