Presentation Transcript

  1. Kingdom Fungi G.Burgess 2009.

  2. Characteristics • Multicellular • Heterotrophic • Cell wall made of chitin • nonvascular • Reproduction asexual (fragmentation) and sexual reproduction (spores). • Extracellular digestion • Absorb materials through mycelium (branching filaments called hypha)

  3. Classification of Fungi • Classified by method of reproduction and reproductive structures. Division Mastigomycota • Produce flagelated spores • cellulose walls

  4. Classification of Fungi Division Amastigomycota • Produce non-motile spores • Chitin cell walls Class Zygomycota • Elongated multiple nuclei that are haploid • Reproduction is asexual by spores Class Ascomycota* • Yeasts reproduce asexually by budding and sexually by forming a sac Class Basidiomycota* • Common mushroom and puffball • Sexual reproduction forms basidiospores on club shaped cells called basidia

  5. Relations with other organisms Lichens • Symbiotic relations between fungi and cyanobacteria, or a green algae • Fungal portion makes the structure, and absorbs nutrients from a substrate. The algal or cyanobacteria portion provides nourishment via photosynthesis.

  6. Questions • Pp. 372 #1-7 • Pp. 373 #2-4 Text: Biology 11, Nelson, 2002.
