fungi kingdom characteristics
Fungi Kingdom Characteristics
  • Eukaryotes.
  • Heterotrophs
  • Cell walls made of chitin
  • Use spores to reproduce.
  • Need warm, moist places to grow.
  • Examples: yeast, molds and mushrooms.
obtaining food
Obtaining Food
  • Digest food outside of their bodies then absorb it by using hyphae
  • Hyphae: threadlike tubes. (Shape of fungi depends on how hyphae used)
  • Exception is yeast which are unicellular.


how hyphae work
How Hyphae Work!
  • Fungus grows hyphae into food
  • Hyphae secrete digestive chemicals into food
  • Hyphae absorb decayed food
reproduction in fungi
Reproduction in Fungi
  • Produce thousands of spores with a protective covering (carried by water and air)
  • If spores land in a warm, moist place they grow.
When moisture is plentiful, fungi reproduce asexually by releasing the spores or hyphae break off and grow on their own.
  • Reproduce sexually by fusing of hyphae, making new spores that are different from both parents.
Since yeast is unicellular, they reproduce by budding. A well fed cell grows from the body of the mother cell and breaks off from the mother.
four classifications of fungi
Four Classifications of Fungi
  • Threadlike - produce spores in their threadlike hyphae (ex. Bread mold)
  • Sac - produce spores in structures that look like sacs (ex. Yeast)

Club - produce spores in structures that look like clubs (ex. Mushrooms)

  • Imperfect- those that cannot reproduce sexually (ex. Penicillin)
phylum zygomycota bread mold
Phylum ZygomycotaBread Mold
  • Hyphae include: Rhizoids (root like) and stolons (stem like)
  • Sexual reproduction is by conjugation (fusing) of hyphae from two different strains, followed by the production of Zygospores.

phylum ascomycota sac fungi
Phylum Ascomycota(Sac Fungi)

Cup Fungi, Yeast, Mildews

  • Named for the reproductive sacs or Asci that form near the tips of the hyphae.
  • Ascospores formed here and released into air when the ascus ruptures.
  • These spores germinate to form new hyphae.
phylum basidiomycota club fungi
Phylum: Basidiomycota(Club Fungi)
  • Mushrooms, Puffballs, Shelf (Bracket) Fungi
  • Underground hyphae intertwine and grow upward to produce a reproductive structure called a basidiocarp = a mushroom
  • Basidiospores are produced on the basidia, found on the edges of the gills.

Boletes: tubes instead of gills

Tubes (not gills) produce spores

Phylum Deuteromycota

(Imperfect Fungi)

  • Athlete’s Foot, Ringworm, Penicillium
  • Called “imperfect” because a sexual reproductive stage has not been observed.
  • Mutualistic relationship between fungi and algae
  • Alga provides food, fungus provides water and a physical environment/home
  • Can be used as an air pollution detector
the lichens life cycle has 3 stages
The Lichens life cycle has 3 stages

1. Crustose (appears grainy)


Many Fungi are involved in Mycorhizzae (symbiotic mutualism) relationships…Over 90% of plants have fungi associated with their roots. The fungus absorbs and concentrates phosphates for delivery to the plant roots. In return, the fungus receive sugars synthesized by the plant.
