Fungi:Botany

-mushrooms

-molds

-mildews

-Eukaryotic

-mulitcellular (except yeast)

-absorbtion nutrition

-cell walls made of chitin

-storage material: glycogen

- Lack of organs

-reproduce by spores

-hypha

-mycelium

-hymenium

-fruiting body

-spores are reproductive cells

-often only 1 cell big

-helps fungi survive

-secretes enzymes outside of fungi

- break down materials externally, then absorbs fungus

-individual threads

• a) Multinucleate or Coenocytic
• *no walls between cells

• b) Septa or cell walls
• * fuzzy things

-mass of hyphae

-area where spaces are formed

-fertile zone

-reproductive structure

-bears spores

-ends in -carp (basidiocarp)

divisions ends in -mycota

bread molds

sac fungi

club fungi

imperfect fungi

a) bread molds

b) no fruiting bofy

• c) asexual reprodcution
• *sporangium: spores
• *sporangiosphore : stalk

• d) sexual reproduction
• *zygote (fertilized egg)
• -inside a zygosporangium

a) sac or cup fungi

• b) ascocarp: fruiting body
• -cup and other shapes
• c) ascus (plural asci)
• -sac-like hypha
• -8 internal ascospores

a) club or gill fungi

• b) basidiocarp: fruiting body
• * not all look like mushrooms

c) basidium : club shaped hyphae, 4 external basidiospores

a) bue green molds

b) no sexual reproductive stage

• C) asexual reporduction
• *conidia (asexual spores) on conidiospores

ex) penicilun, aspergills

• a) parasites
• -living on live organisms
• *fungi on people and plants

• b) saprophytes
• -living on dead organisms
• *wastes, wood rot

• a) decomposers
• -breaks down and recycle nutrients in soil
• *saphrophytes
• b) mutualists
• -two organisms living together, benefitting
• *lichens: fungus gets food, algae get shelter

• c) fungi as food
• *yeasts and cheese
