What Are Fungi? 3 main Characteristics: 3 main Characteristics: Eukaryotes – cells with nucleus and organelles (either unicellular or multicellular organisms) Eukaryotes – cells with nucleus and organelles (either unicellular or multicellular organisms) Heterotrophs- feed on other organisms Heterotrophs- feed on other organisms Reproduction- all use spores Reproduction- all use spores

Fungi Structure Fruiting body/Cap- underside may have ridges called gills Fruiting body/Cap- underside may have ridges called gills Stalk / Mycelium Stalk / Mycelium Hyphae- tubelike extensions that make up stalk and “roots” Hyphae- tubelike extensions that make up stalk and “roots”

How Fungi get food Most Parasites of living or dead organisms- Most Parasites of living or dead organisms- Hyphae release enzymes that liquefy organic material Hyphae release enzymes that liquefy organic material Liquefied material then slurped up and used for growth and production of spores Liquefied material then slurped up and used for growth and production of spores

Fungi Reproduction Good Conditions- fission/ asexual Good Conditions- fission/ asexual Bad Conditions- fusion/ sexual Bad Conditions- fusion/ sexual
