    Study Notes

    Fungi Study Notes

    • The scientific term for the study of fungi is mycology.

    Fungi Classification and Characteristics

    • Penicillium is the fungus used in the production of Penicillin.
    • Chitin provides rigidity and support to the cell walls of fungi.

    Fungal Infections and Disease

    • Fungi are more likely to cause diseases in immunocompromised individuals.

    Cellular Composition of Fungi

    • Phospholipids are the primary component found in the cytoplasmic membrane of fungi.

    Medical Applications of Fungi

    • Ergot fungus is used to induce uterine contractions.

    Fungal Reproduction and Spores

    • The primary function of endospores in fungi is to withstand extreme environmental conditions.
    • Ascomycetes are the type of fungi that produce mycelia and are responsible for the shape and color of fungus.

    Fungal Structure and Growth

    • Aerial mycelium provides the structure for the fungus to grow above the substrate.
    • The characteristic mode of reproduction for yeasts is budding.
    • Dimorphic fungi grow partly as yeasts and partly as elongated cells resembling hyphae.

    Fungal Growth and Development

    • The primary factor causing the deceleration phase in the normal growth curves of fungi is nutrient depletion.
    • Vegetative mycelium is responsible for nutrition in fungi.
    • The primary mode of reproduction for molds or filamentous fungi is the production of conidiospores.
    • Unicellular budding yeast's primary function in fungi is to undergo rapid cell division.
    • Dimorphic fungi can be classified as forming molds (filaments) at ambient temperatures.
