General Characteristics of Fungi
|
Saphrophytes, Parasites(sometimes), Unicellular-3.5 miles in diameter, Evolved From Protists, Classified by Reproduction.
|
|
General Structure of Fungi
|
Hyphae, Septum, Mycelum, Store food as glycogen
|
|
Divisions:
Zygomycota |
Black Bread Mold (wheat molds): 1,000 species, reproduce sexually and asexually spores, hyphae do not have septa
|
|
Basldiomcotes
|
mushrooms, toadstoles, smuts, rusts- also likes flour
|
|
Ascomycotes
|
mildrew, yeast, thrush, penicilin, aperisillas
|
|
Deuteromycotes
|
ringworms, athletes foot. 25,000 species, no known sexual
|
|
Symbitotic Relationships
|
...
|
|
Lichens
|
Fungus + Green Algae
Fungus forms a dense web of hyphae in which the algae can grow in and in return, they get food for both organisms |
|
Mychorrihiza
|
Fungus + plant roots, does Nitrogen fixation
Fungus increases the absorptive surface of the plants roots and helps to maintain water in the soil around the plant in return for organic nutrients to survive. |
|
Plant Kingdom

...
|
|
Importance of Plants
|
produce oxygen + uses carbon Dioxide, food, Nutrients in the soil, decomposers, clothing, wood, energy, paper, pencil, Medicine, Herbs.
|
|
Reproduction
|
Assexual:Shoots, Cuttings, Grafting
Sexual:Gametes(male in polen, female in ovule) |
|
Classification of plants
|
by vacuole system
|
|
Bryophytes
|
moss, non-vascular, low to the ground, does most of the photosynthesis
|
|
Vascular Plants
|
live anywhere, have roots, stems, and leaves
|
|
Seedless (4 divisions)
|
Examples: ferns, horsetails
also dominated during the dinosaur age. |
|
Gymnosperms
|
Examples:cycads, ginkos, Spruce, Pine, Conifers
Leaves are needles don't lose eaves during winter |
|
Anglosperms=2 divisions
|
dominant group, flowering plants, co-evolution with insects
Ex: Herbs, shrubs, grasses, trees |
|
Monocot Features
|
parellel veins in leaves, 3 part symmetry in flowers, no annual rings, no wood, can have bulbs for roots
|
|
Monocots Examples
|
grass, wheat, oats, lilies, rye, corn, rice, onion, palms, bamboo
|
|
Dicot Features
|
midrib with veins in leaves, multiple leaf symmetry, primary and secondary roots system, flowers with 2, 4, 5 petals, stem with vascular tissue in rings, wood, bark, fruit
|
|
Dicot Examples
|
most trees, fruit
|
|
Structures of Cells
|
...
|
|
Darenchyma
|
thin cell walls
|
|
Collenchyma
|
thicker cell walls
|
|
Sclerenchyma
|
super thick cell walls
|
|
Xylem
|
dead like wood (scleranchyma cells)
|
|
Phloem
|
primarily Collenchyma cells
|
|
Meritemsiu
|
actively dividing cells (darenchyma cells)
|
|
what is the complex cargohydrate that makes up the cell walls of fungi called?
|
chitin
|
|
What is the basic structural unit of a multicellular fungi called?
|
Hyphae
|
|
What is the network of Hyphae called?
|
Mycelium
|
|
What are the cross walls that divide hyphae called?
|
septa or septum
|
|
Fungi are decomposers, true or false?
|
True
|
|
Are fungi heterotrophs or autotrophs?
|
Heterotrophs
|
|
What are stolons?
|
There are the horizontal hyphae that grow on Rhizopus that produce mycelium.
|
|
What are rhizoids?
|
Hyphae that penetrate the food and anchor the mycelium in the bread. Rhizoids secret enzymes for extracellular digestion and absorb the excess nutrients.
|
|
When do zygomycotes reproduce sexually?
|
When the bread becomes dry or other environmental conditions occur.
|
|
What are zygospores?
|
Zygospores are thick walled spores that withstand unfavorable conditions, occur when rhizopus reproduces sexually.
|
|
What are Ascomycotes called?
|
Sac fungi?
|
|
What is the largest phylum of fungi?
|
Ascomycote
|
|
What is an ascus?
|
Tiny sac like structure where the sexual spores of the fungi develop.
|
|
What are conidiophores?
|
Conidiophores are fungi fungal hyphae during asexual reproduction for ascomycotes.
|
|
What is the name for the spores produced by Ascomycotes during sexual reproduction?
|
Ascospores
|
|
What are Conida?
|
They are chains or clusters that develop from tips of conidophores
|
|
What shape are the hyphae for basidiomycotes and what are they called?
|
Club shaped and basidia. That's why they are called club fungi.
|
|
What are basidiospores?
|
spores produced in basidia sexual reproduction.
