symbiosis
Symbiosis
  • Lichens
  • Mycorrhizae
general characteristics
General Characteristics
  • Eukaryotic
  • Mostly multicellular
  • Mostly haploid
  • Chemoheterotrophic
    • Extracellular digestion via exoenzymes
      • Saprobes (decomposers)
      • Parasites
      • Mutualisticsymbionts
asexual reproduction1
Asexual Reproduction

Spread by growth…

…and spore dispersal

sexual reproduction1
Sexual Reproduction
  • Plasmogamy
    • Fusion of cytoplasm of hyphae
    • Produces heterokaryotic cells
sexual reproduction2
Sexual Reproduction
  • Karyogamy
    • Fusion of nuclei
    • Produces diploid zygote
  • Meiosis produces haploid spores
