Kingdom Fungi Chapter 26, Fungi Membrane-enclosed nuclei, mitochondria and other membranous organelles Eukaryotic heterotrophs Digestion is outside of the body Infiltrate food source, secrete digestive enzymes onto food, then absorb predigested food Cell walls with chitin (complex CHO) Resistant to breakdown by most microorganisms Fungi Structures Fungi include: unicellular yeasts (simplest) filamentous, multi-cellular molds (complex) have long, threadlike filaments (hyphae) - elongate and infiltrate food source branch to form a tangled mass (mycelium); grows into host Some alternate between yeast form and hyphae Fungus Body Plan Reproduction (asexual) Budding is also a form of asexual reproduction – quick and with little re-assortment e.g. yeasts Reproduction (sexual) Involves meiosis and generates new genotypes Hyphae of two genetically haploid (n) compatible mating types unite (facilitated by pheromones) Zygote (2n); meiosis results in haploid spores that can now form new hyphae Review: A Generic Fungal Life Cycle Fungi belong to the Opisthokonts; a monophyletic group that includes members of three kingdoms: fungi (Kingdom Fungi) animals (Kingdom Animalia) and the choanoflagellates (from the Kingdom Protista) As opisthokonts, fungi are more closely related to animals than to plants:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
