Kingdom Fungi
I. General Characteristics1. Found almost everywhere2. Used to be classified as plantsbecause they were anchored and have cell walls, but are now a distinct Kingdom.
Structure of Fungi
A. Structure of Fungi1. Most fungi are Multicellular2. Hyphae - threadlike filaments whichdevelop from fungal spores3. Mycelium - network of filaments(hyphae)4. Chitin - complex carbohydrate whichmakes up the cell walls of fungi
Mycelium - network of filaments (hyphae)

II. How Fungi get their Food
• A. Extra cellular digestion• 1. Fungi are heterotrophs - which means theydepend on other sources for supply of energy• 2. Extra cellular digestion- breakdown foodoutside of the cell by use of powerful enzymes• 3. Parasite fungi absorb nutrients from theirhosts by using specialized hyphae calledhaustoria
III. Reproduction
• A. Fungi may reproduce asexually orsexually. Most produce spores which landon favorable conditions and grow.
• B. Budding- a form of asexual reproductionwhere a new individual grows out andseparates from parent cell.
• C. Sporangium- a sac in which spores areproduced
IV. Fungi are divided into 4 phyla
• A. Zygomycota (black bread mold)
B. Ascomycota- Sac Fungi (blue-green, red & brown molds, morels & truffles, yeast)
C. Basidiomycota- Club Fungi (mushrooms, puffballs, bracket fungi)
D. Deuteromycota- imperfect fungi(Penicillium, athletes foot, ringworm)
Symbiotic Relationships
• 1. Mycorrhiza- Fungus in a symbioticrelationship with the roots of a plant
2. Lichens- a symbiotic association betweenfungus and a green alga orcyanobacteria• Fungus receives nutrients from plant andplants receive moisture & ground stability
