Lab 2 Flashcards
what are the main eukaryotic decomposers on the planet
fungi
how do fungi eat
absorb live food but a majority is already dead
what is mycelia
networks that fungi spend most of their lives as
what is mycelia consist of
hyphase
what is hyphae
tissues of fungi that are filamentous strands of cells that are thin but grow almost infinitely long
what are cell walls of fungi and hyphae made of
chitin
what kind of digestion do fungi do
external digestion
what is external digestion
exude enzymes outside of their body onto their food, enzymes break down the food into smaller molecules and fungi absorbs it into their hyphae
some fungi have _______________ that are specialized to break down chemicals that few other organisms can use as food
evolved enzymes
what organisms is some of the only that can break down lignin and cellulose
basidiomycota (club fungi)
why is it hard to detect mycelia
hyphal networks are very thin and buried underground or in their food source
what are the parts of a fungus that stick out of the ground
reproductive structures which are mushrooms
how much of the biomass of a fungus is in the reproductive structure and mycelial network
small fraction of biomass is in reproductive stucture, most of it comes from mycelial network below
what are the 3 fungal groups
Zygomycota, Basidiomycota, Ascomycota
what fungal groups are true clades, and which ones don’t represent a Zygomycota
true clades -Basidiomycota and Ascomycota; not a true monophyletic group - Zygomycota
