Kingdom Fungi

Distinguishing Characteristics Eukaryotes Nuclei in cells Multicellular Cell walls (chitin) Heterotrophs Sessile Sexual & Asexual Reproduction

Distinguishing Characteristics Absorbs food through hyphae Largest living thing Mycelia– masses of hypha Chitin walls (chitin is same material found in exoskeletons of animals)

Alternation of Generation Sexual – Hyphae “mate” results in 2 nucleus cell called dikaryote. – Cells fuse and you get cell with twice the genetic information – Undergoes meiosis to split back to normal – Spores result  germination and new hyphae Asexual – Hyphae produce asexual fruiting body that produces spores

Animalia Chytridiomycota Zygomycota Ascomycota Basidiomycota

Chytridiomycota Flagella in one stage of life Live in water Cell walls unseparated Hyphae

Chytridiomycota Primitive aquatic fungi. They are characterized by having gametes that are motile by means of flagella species

Zygomycota Resistant dikaryotic spores Spores live for months or years… Bred molds…

Zygomycota (Coenocytic Fungi) Zygomycota Form sexual spores called zygospores. They form when the nuclei at the ends of two hyphae fuse together in a process of fertilization to form a zygote. Fungus growing on moss, to the right is a magnified view.

Zygomycota:Black Bread Mold Rhizopus nigricans.

Ascomycota “Sack” fungi Reproductive sack forms where sexual reproduction happens

Ascomycota:Cup Fungus Ascomycetes Their sexual spores (ascospores) are enclosed in tube- like sacs known as asci. Neurospora crassa is an ascomycete mold that was important in studies of genetic linkage. With lichen surrounding Orange fairy Scarlet fungus Asci

Basisiomycota Produces “clubs” mushrooms that are swollen masses of dikaryotic cells.

Basidiomycota: Club Fungus Basidiomycetes Their sexual spores, or basidiospores, are formed on complex fruiting body structures called basidia. Included in this class are some of the most complex fungi, including mushrooms and puffballs. puffballs leucocoprinus fragilissimus Coral fungus
