Note Book 9 FUNGI
2
Characteristics

• Heterotrophic (fungi are NOTS PLANTS)
• Must consume their food
• Major decomposers

3
Characteristics

• Made up of filamentous bodies
• Fungi do not have tissues
• Fungi have long filaments
• Filaments weave to form the body

4
Characteristics

• Cells
• Cell walls are made of Chitin

CHITIN
5
Characteristics

• Fungi obtaining Nutrients
• Secrete digestive enzymes
• Enzymes break down food
• Fungi then absorb the food

6
Characteristics

• Fungi Reproduce
• Asexually
• Sexually
• Spores (kind of like egg and Sperm)
• Release haploid spores that were formed asexually
  or sexually.

7
Structures

• Hyphea
• All fungus except yeast are made of hyphea
• Hyphea are long slender filaments
• Each filament is a long string of cells where the
  cytoplasm flows freely through each cell.

8
Structures

• Mycelium
• Tangled mass of hyphea
• The whole shebang of all the hyphea!

9
Classification

• Fungi are classified by sexual reproductive
  structures.
• What about the Asexual Fungi?
• Classified as deuteromycetes
• Penicillium is in this group!

Penicillium
11
Sexual Reproducing Fungi
12
Zygomycetes (bread mold)

• Have
• Zygosorangia thick walled reproductive
  structure
• Stolons mycelium
• Rizhiods hyphea

13
Zygomycetes
14
Ascomycetes (form Sacs)

• Sexual reproductive Structure
• Ascus- Sac like structure
• Yeasts are asexual reproduce by budding

15
Ascomycetes
Cup Fungi
Morels
16
Ascomycetes
Yeast
Truffles
17
Basidiomycetes

• Most familiar with
• Sexual reproductive structure
• Basidium club shaped mushroom cap
• Spores are produced in the gills of the basidium

18
Basidiomycetes
Rusts
19
Basidiomycetes
Corn Smut
20
Basidiomycetes
Mushrooms
Puffballs
21
Good Fungi

• Some Fungi Form Symbiotic Releationships
• Symbiosis relationship between 2 organisms
  living close to each other.
• Mutualism when both organisms benefit from
  their symbiotic relationship.

22
Mutualistic relationships

• Mycorrhizae
• Fungi and vascular plants

23
Mutualistic relationships

• Lichens
• Between algae and fungi

24
Lichens
25
Human Diseases

• Fungi can cause human disease

Yeast Thrush
Yeast Diaper Rash
26
Human Disease
Histoplasmosis , from guana (bat droppings)
Coccidioidomyces, Soil Fungus
27
Human Disease
