Fungi Kingdom - Nick Williams' San Marin Science

Fungi Kingdom - Nick Williams' San Marin Science

Kingdom Characteristics Eukaryotic Heterotrophs digest food outside of body then absorb it Can be saprobes (get food from decaying matter ) or parasites Cell walls made of Chitin Multicellular, except for yeast

Structure and Function Mycelium Fungi body made up of many tiny filaments in a tangled mass Hyphae the individual filaments that make up the mycelium One cell thick Some have cross walls, some dont (draw example)

May contain many nuclei Fruiting Body reproductive structure that grows from the mycelium Fungus Structure Reproduction Both asexual and sexual

Asexually Produce spores (2N) in Sporangia Or fragmentation break off Sexually Two mating types (+) or (-) Gametes (N) are produced in a structure called a gametangium

Common Molds (Zygomycota) Examples Bread, cheese molds Terrestrial Rhizoids hyphae that extend into bread Stolons hyphae on

the surface Sporangiophores hyphae that push up into the air Sac Fungi (ascomycota Examples yeast, cup fungi Ascus fruiting body

that forms Club Fungi(Basidiomycota) Examples mushrooms, bracket or shelf fungi Basidium fruiting body which has gills lined with basidia

(spores) Imperfect Fungi (Deuteromycota) Examples Athletes foot, penicillium Only reproduce asexually Symbiotic relationships - Lichen

Mutualistic relationship between a fungi (usually an ascomycete) and a photosynthetic organism (usually green algae) Resistant to drought, cold, or harsh environments

Very sensitive to air pollution Symbiotic relationships Mycorrhizae Mutualistic relationship between fungi and plants Fungi helps plant with water

absorbtion Plant gives fungi food Found on 80% of plants Hidden fungi - Cryptomycota Just discovered yesterday (seriously)

Life cycle includes swimming stage and stage living symbiotically with green algae No chitin cell wall discovered yet so it might not even be a fungi!??!?!

These are the jokes Why did the mushroom get invited to so many parties? Why did the algae and and the fungus get married?
