Reproduction
Reproductive structure at the tips of the hyphae and extend high in the air so that the air current will carry them to spread
Yeast
Phylum - Ascomycota
-Saccharomyces Cerevisiage
-Candida Albicans
Saccharomyces Cerevisage
Bakers yeast
Candida Albicans
Causes thrush
Thrush
Milk white lesions forming on mouth, lips, and throat
Budding
New formation of cell
Mushrooms
Phylum - Basidiomyota
- Basidium
Basidium
Named for their characteristic club shaped sexual reproductive structure named Basidium
- reproduce sexually
Fungi Imperfecti
Phylum - Deuteromycta
- asexual reproductive structure
- Penecillum
- Aspergilus
Penecillum
Provides penicillin
Aspergilus
-used for fermenting soy sauce
- commercial production of citric acid
Fungal Association
- Lichen
- Photosynthetic partner
- Fungal partner
Lichen
Symbiotic association between a fungus and a photosynthetic partner
- sensitive to pollutants
- absorbs chemicals for food
- acid rain or lots of rain destroys it
- lichen will die
Photosynthetic partner
Provides energy rich compounds for both partners
Fungal partner
Protects from the environment and provides mineral nutrients
Tough fungus
Can live in
- dessert
- Arctic
- bare soil
- tree trunks
- sun baked rocks
survives drought and freezing by becoming dormant
Mycorrhizae
Symbiotic relationship of certain fungi with roots of plants
- fungi filaments transfer phosphorous and minerals to roots of plant and plant supplies carbohydrates to fungus
Fungi characteristics
-Decomposers
-Heterotrophic
-Filamentous bodies
-Wall made of chitin
-Nuclear mitosis
Decomposer
Breaks down organic molecules (made of carbon) and changes them
Filamentous bodies
Have long slender filaments which weave tightly together to form a fungus body
Walls made of chitin
Tough material in the hard cell wall
Nuclear mitosis
In dividing muscular cells, the nuclear interphase remain intact from prophase to anaphase
Penicillium
Mold on a lime
Hyphae
All fungi except yeast have bodies composed of slender filaments called fungi
Mycelium
When hyphae grow together
Septa
The walls that seperate
Food digestion
-Fungi digests food outside their bodies through the tips of the hyphae
-They secrete powerfull digestive enzymes that break down the organic matter into smaller molecules
-The fungi absorbs these molecules and uses them for energy
Food digestion
Leaves
Animal corpses
Waste
Paper
Cardboard
Petroleum
Paint
Fruit
Vegetables
Bread
Meat
Sticks
Benefits of fungi
-Produce carbon dioxide and ethanol
-Pungent flavors and aromas
-Antibiotics
-Drugs - Cydosporine
Produce carbon dioxide and ethanol
Wine and beer
Drugs - Cydosporine
-Drug derived from fungus that lives in soil.
-Suppresses the reaction of the immune system
-Causes the ability to allow a transplanted organ
