Fungal Characteristics

Fungal Characteristics

1)Cell wall made of Chitin

2)Heterotrophs and major Decomposers

3)Body is made of Long filaments of hyphae which form a mycelium

4)Reproduce sexually and asexually

Asexually by spores

Sexually by mating of hyphae filaments

Kingdom Fungi – you must know 5 Major Phyla

Kingdom Fungi – you must know 5 Major Phyla

Phylum Zygomycota = the Bread Molds

Rhizopus – black bread mold

Oomycota = the Water Molds

Water mold, potato blight, mildew

Phylum Ascomycota = the Sac Fungi

Yeast, morels, truffles

Phylum Basidiomycota = the Club Fungi

Mushrooms, puffballs, bracket fungi, rusts, smuts, toadstools

Phylum Deuteromycota = the Fungi Imperfecti

Slide 11

Zygomycota (Rhizopus) the Common Molds

Zygomycota (Rhizopus) the Common Molds

-are primarily decomposers

-asexual spores may be produced in sporangia

-sexual reproduction occurs between + and – strains forming a 2n zygote; a zygospore develops and may lie dormant for a long period of time; meiosis occurs just before germination

-only the zygote is diploid; all hyphae and asexual spores are haploid

Slide 12

Zygomycota – common molds

Zygomycota – common molds

The fungal mass of hyphae, known as the MYCELIUM penetrates the bread and produces the fruiting bodies on top of the stalks

Mycelia = a mass of hyphae or filaments

Slide 13

Rhizoids = root-like hyphae

Rhizoids = root-like hyphae

The zhizoids meet underground and mating occurs between hyphae of different molds (SEXUAL REPRODUCTION)
