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
