Lecture Exam 3 Study Guide Kingdom Fungi Introduction to Plantae Bryophytes Introduction to Tracheophytes and Pterophytes. Kingdom Fungi Defining Fungi ● Singlecelled (yeast) or multicellular ● Sexual or asexual reproduction ● Extract and absorb nutrients from their surroundings ● Closest kingdom related to animals Anatomy: ● Grow in hypha (hyphae pl.) tangle of tiny filaments ○ What is the benefit Enormous surface area for digestion ● Mycelium mass of connected hyphae ● Fungal walls include chitin (yes, the same stuff found in exoskeletons of arthropods) ○ In contrast: cell wall of a plant or protist cell is composed of cellulose ● Septum cross walls separating the hyphae ○ BUT there is usually an opening between 2 cells/the septum isn’t complete which explains why fungi grow so quickly→ cytoplasm can stream quickly back and forth, carrying nutrients to the growing tips of hyphae Reproductive Cycle: ● Fungi nucleus is typically haploid (1n) ● Only the zygote is diploid (2n) ● Diploid zygote divides by meiosis to form haploid species ● Spores germinate into haploid hyphae Hyphae may have more than one nucleus: ● Monokaryotic 1 nucleus ● Dikaryoti 2 nuclei Sometimes many nuclei intermingle in the common cytoplasm of the fungal mycelium ● Heterokaryotic nuclei from genetically distinct individuals ● Homokaryotic nuclei are genetically similar to one
