Transcript of Biology Lesson 5.6
Lesson 5.6 FungiCharacteristics:Belong to Kingdom FungiIncludes mushroom, molds, lichen, yeast and mildewNonvascularLack chlorophyllDepend on other organisms for food (heterotrophs, most saprophytes)
Lesson 5.6 FungiCharacteristics:
Most multicelled except yeast
Have filaments that make up the body called hyphae
Hyphae together make up the main body called the mycelium
Lesson 5.6 Fungi
Terms:Heterotrophs – organisms that can not produce their own food.
Autotrophs – organisms that can make their own food.
Saprophytes – get nutrients from dead organisms
Lesson 5.6 Fungi
Terms:
Mycologist – scientist who studies fungi
Lesson 5.6 Fungi
Importance of Fungi:Great decomposersSome parasiticYeast important to bread makingMushrooms people like to eatPenicillin – important class of antibiotics
Lesson 5.6 Fungi
Types of fungi:1. Club Fungi Produce spores in microscopic club-
shaped structures called basidia Includes mushrooms, toadstools,
rust and smuts Saprophytes Many edible
Lesson 5.6 FungiTypes of fungi:
1. Club Fungi
Many rust and smuts cause great crop damage ex. Wheat rust and corn smut
2. Molds Ex. Bread mold, cheese mold Penicillin comes from Penicillium
mold Some harmful to crops
Lesson 5.6 FungiTypes of fungi:
1. Club Fungi2. Molds
3. Sac Fungi Have saclike spore-producing
structures Ex. Yeast and mildew Carry out alcoholic fermentation
produce CO2 makes bread rise
Lesson 5.6 FungiTypes of fungi:
1. Club Fungi2. Molds
3. Sac Fungi Reproduces by budding when
conditions are good and spores called ascus when conditions bad and can remain dormant.
Lesson 5.6 FungiTypes of fungi:
1. Club Fungi2. Molds3. Sac Fungi
4. Slime molds Jellylike organisms found on bark
of fallen trees Brightly colored (bright red,
yellow, orange) Eat bacteria or other organic stuff
Lesson 5.6 FungiTypes of fungi:
1. Club Fungi2. Molds3. Sac Fungi4. Slime molds
5. Lichens Symbiotic relationship between
algae and fungus Algae is photosynthetic and
provides food Fungus provides water and
minerals for algae
