  • FUNGI
    • Nutrition: Heterotrophs
      • Organic substrates to get carbon for growth
    • Filamentous bodies
      • Body mostly mycelium
        • Interwoven mass of one cell thick hypha
      • Cell wall
        • Chitin: Tough, slightly flexible
      • Unable to move about
        • Hyphae grow rapidly in all directions
          • Fungal mycelium infuses quickly in suitable substrates
            • Sometimes grow together and differentiate into reproductive structures
          • Why form large network?
            • Larger surface area to volume ratio, efficiency of absorbtion increases
    • Reproduction
      • Spores-> Germination-> Mycelium-> Fruiting Body
      • Haploid (n), produced by mitosis, Diploid (2n) only forms during sexual portion.
      • Asexually
        • Default, under stable conditions, can colonise fast, lesser genetic variation so more likely to die
          • Produce spores
      • Sexually
        • Enivironmental change/stress, more genetic variation, slower
          • Produce spores
        • Occurs when hypha comes in contact with compatible hypha              (+ and -) which fuse so the 2 nuclei share a cell (plasmogamy and Dikaryon)
      • Propagate by spores
        • Transported by sticking to animal fur, wind, self-propulsion
        • Produced in large numbers
  • Septum has pores, allows organelles to flow through
  • Reproduction
    • Spores-> Germination-> Mycelium-> Fruiting Body
