1. Kingdom Fungi
Unit 2 - Biodiversity

2. 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

3. 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.

4. Structure
Hyphae
Whole Structure

5. 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.

6. 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.

8. Fungi and you Decomposers Food (mushrooms, truffles, etc.)
Positive Aspects of Fungi
Negative Aspects of Fungi
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
