1. FUNGI!

2. FUNGI!! Mostly multi-cellular, but can be unicellular Can not move
Heterotrophs
Decomposers; absorb nutrients

3. Fungus Structure Hyphae: thread-like filaments that develop spores
Septa
Mycellium
Hyphae: thread-like filaments that develop spores
Septa: cross walls that divide hyphae into individual cells
Mycellium: the network of branched hyphae

4. Fungus Structure Mycellium is made of different kinds of hyphae
3 main functions
Anchor fungus
Invade food source
Form reproductive structures
Cell walls made of Chitin
Provides strength and flexibility to each fungal cell

5. Obtaining Energy Heterotrophic Decomposers
Process used to digest food: Extracellular digestion
Hyphae grow into cells of organic material and release digestive enzymes that break down material and sent it thorough hyphae into the fungus

6. Types of Fungi: Zygomycote
Bread Molds
Food Molds

7. Types of Fungi: Basidiomycotes
More Familiar
Mushrooms, puffballs, stink holes, and nest fungus

8. Types of Fungi: Ascomycote
Largest division
Sac Fungus-small sacs of fungus
Used in genetic research, bread and alcohol production
Examples: yeast

9. Types of Fungi: Deuteromycotes
Used in vaccines: penicillin, antibiotics
Examples: Penicillium

10. Types of Fungi: Chytridiomycotes
Aquatic fungi that provide clues about the evolution of fungi
Once classified as protists because they have a flagella
Mainly saprophytes, but some are parasites
One of the reasons for the decline of amphibians

11. Types of Fungi: Glomeromycota
Form symbiotic relationships with plants
Forms a mycorrhiza, symbiotic relationship between the fungus and plant roots
Reproduce asexually with spores

12. Fungal Reproduction
Sexual or asexual, depending on species and environmental conditions
Three methods:
Fragmentation: Asexual
Budding: Asexual
Spore Formation: Asexual OR Sexual

13. Fungal Reproduction Fragmentation Budding Spore Formation
Multicellular. Pieces of hyphae are broken off and grow into new mycelia. Ex: Deuteromycotes
Budding
Unicellular. After mitosis, new cell “buds” from the original. Ex: Zygomycotes
Spore Formation
Multicellular. Spores produced in a sporangium. Once spore is in a favorable environment where new mycellium is formed. Ex: Basidiomycotes, Ascomycotes, Zygomycotes

14. Symbiosis In Fungus Mutualism: Fungus and photosynthetic partner
Lichens: Fungus and Green Algae
Parasitism: Absorb nutrients from living things with special hyphae that help absorb the host’s nutrients
Saprophytes: Decomposers; feed on dead waste
