Kingdom: FungiDOMAIN: EUKARYA
MOLDS, MUSHROOMS, MILDEWS, LICHEN, AND YEAST
Characteristics
Have a nucleus (eukaryotic)
Have a cell wall but NO chloroplasts
Mostly multi-celled
Generally reproduce both asexually and
sexually
Mostly decomposers
Question: How are fungi different from
plants?
1. Plants have a cell wall, but fungi do not.
2. Fungi do not make their own food, but plants
do
3. Fungi are prokaryotic while plants are
eukaryotic
Examples
Put pictures here
Structure
Hyphae: cells connected in long tubes,
substances move easily through them (diffusion)
Structure
Some have: cap, gills, stalk,
spores, and underground hyphae
Energy
Decomposers (Heterotrophs)
1. Grow hyphae on and into food source
2. Hyphae ooze digestive enzymes that break
down the food into small molecules to be
absorbed
Most fungi do respiration, but some do
fermentation (yeast)
Asexual Reproduction
Budding: a small yeast cell grows from the
parent cell (fission)
Asexual Reproduction
Spores: most fungi produce tiny new
cells that can grow into new fungi
Sexual Reproduction
Some fungi….especially in unfavorable conditions
1. Intertwine their hyphae and exchange genetic
material
2. Produce spores that are different from the
parents
3 Major groups of fungi:
Zygote Fungi
Sac Fungi
Club FungiZygote
Fungi
The Role of Fungi
Food: yeast for bread and alcohol, molds for
cheese, mushrooms on salads
Environment: recycling dead plant matter
Medicine: Penicillin was the first antibiotic
discovered
Disease: Plant disease ( Dutch elm disease) and
human disease (ringworm or athletes foot)
The Role of Fungi
Symbiosis: helping plants grow healthier when
hyphae grow on or into plant roots
Lichens: “pioneer organisms”, indicate levels of
pollution
Poison: some cause hallucinations, or worse
