  1. Mycology: The study of fungi

  2. Characteristics • Eukaryotic (have a nucleus) • Heterotrophs(most are decomposers) • Some are unicellular (yeast) • Most are multicellular • Cell wall • Four main types including lichen

  3. Examples: • Fuzzy, threadlike molds • Unicellular yeast • Mushrooms • Lichen (fungus and algae)

  4. Acquiring energy • Fungi cannot eat or engulf food. They live on their food source. • Fungi obtain nutrients by secreting digestive juices through their hyphae and absorbing the food. • A mass of hyphae is called mycelium.

  5. Reproduction • Most Fungi reproduce both sexually and asexually. • Spores are tiny reproductive structures formed in fruiting bodies from which new fungi grow. • Asexual reproduction in yeast is called budding

  6. Effects of Fungi Benefits: 1. Many fungi are decomposers, make some foods(bread, mushrooms), produce antibiotics (penicillin) 2.Fungi grow into plant roots And help them grow better. 80% of all plants have fungal partners on their roots.

  7. Effects of Fungi Diseases: Plant diseases: Dutch Elm, corn smut, wheat rust Human diseases: athlete’s foot, ring worm, food spoilage

  8. Lichen • A relationship between a fungus and an alga. • Fungus gets food from the alga and the alga gets water, minerals and shelter from the fungus.
