KINGDOM FUNGI
Unit 2 - Biodiversity
Kingdom Fungi
Eukaryotic Mostly Multicellular
Yeasts are unicellular Heterotrophic by absorption Walls made of CHITIN Decomposers
Live off dead or decaying matter Parasites
Live off a living host
Structure of Fungi
Composed of hyphae Branched filaments (groups of cells)
surrounded by a hard chitin cell wall. Makes up the body of the fungi
All except yeast, they are unicellular Mycelium
Mass of hyphae, similar to the roots of a plant
The visible part of the fungus (both in mold and mushrooms) is called the fruiting body.
Structure
Hyphae Whole Structure
How does fungi reproduce?
Reproduce by spores Reproductive cells
Can reproduce both sexually and asexually
Held by the hyphae in a sporangia (spore case)
Where new spores land, new fungus will grow.Think about how easily mold spreads on bread, or when you chop up a mushroom with the lawn mower and new mushrooms pop up.
Spores are spread by wind, water, animals, etc.
How do they eat?
Heterotrophic decomposers (some parasites).
Secrete digestive enzymes that decompose complex molecules into simple molecules like sugars and carbs. Molds digestive carbs in things like
bread Mushrooms digest carbs and cellulose
from the cell walls of wood and plant cells.
Fungi and you
Decomposers Food (mushrooms,
truffles, etc.) Lichens grow on rocks
and help produce soil Yeasts are used in
baking and brewing industry
Antibiotic Production
Food Spoilage Diseases
athlete’s foot, ringworm, plant blight (American chestnut)
poisonous mushrooms
