Goal #5: FUNGI They’re not plants!
A. CELLS Multicellular/Unicellular Eukaryotic
B. GENETIC MATERIAL They have DNA found inside the nucleus.
C. STRUCTURE Multicellular fungi are made of thin filaments called HYPHAE. Each hyphae is only one cell thick!
D. REPRODUCTION C. Reproduction 1. Asexually • hyphae break and spread spores • spores = reproductive cell formed by mitosis that grows into new organism • Spores spread by wind and insects, then settle and grow
2. Sexually • Two different mating types • Plus (+) and minus (-) • (+) and (-) meet and forms gametes • When 2 gametes fuse, there is a new offspring!
E. NOURISHMENT HETEROTROPHSthat digest their food outside their body and then absorb it • Some absorb nutrients from decaying matter in the SOIL. • Some live as parasites absorbing nutrients from LIVING HOSTS.
F. RESPIRATION Not all fungi are alike! • Obligate aerobes • Obligate anaerobes • Facultative anaerobes
G. Movement Fungi DO NOTmove on their own!
1. Symbiosis • Some Fungi live together with other organisms • Fungi + Algae = Lichen • Fungi + Bacteria = Lichen • Fungi + Plant Roots = Mycorrhizae
2. Fungi can be HELPFUL • Fungi are the DECOMPOSERS- a very important part of every ecosystem • Fungi RECYCLE NUTRIENTSby breaking down dead organisms and their waste products!
3. Fungi can be harmful • Parasitic fungi can cause diseases. • Corn smut • Wheat Rust • Athlete’s Foot/Ringworm • Yeast Infection/Thrush
III. Classification -based on their reproduction
A. Common Molds - Phylum Zygomycota - produces spores - hyphae with no cross walls - ex: meat, cheese, and bread mold
B. Sac Fungi - Phylum Ascomycota - largest phylum of fungi - ex: cup fungi, yeasts - yeasts are the only unicellular fungi & reproduce asexually by budding - yeast is used for baking (alcoholic fermentation)
C. Club Fungi - Phylum Basidomycota - ex: mushrooms (most are poisonous!) -shelf fungi -puffballs -earthstars -jelly fungi
D. Imperfect Fungi - Phylum Deuteromycota -not in other phylum because cannot classify sexual life cycle - resemble all other groups of fungi
