Water and Downy Molds
Why are molds important?
For breaking down dead-matter and providing nutrients
Why makes fungi closely related to animals?
They are heterotrophs, produce, melanin, and have a similar cell wall make up
What were the first Fungi?
Prototaxites
What are characteristics of prototaxites?
They were the earliest fungi, grew very tall and wide, and were spread out
What is the mycelium?
The underground body of fungi
What is a mushroom?
The fruiting body of fungi that sprout above ground
Why do fungi have fruitng bodies?
To attract animals to disturb them and spread their spores
Which hyphae does not have barriers?
Coenocytic Hyphae
Which hyphae has barriers between cells?
Septatc Hyphae
Why are hyphae spread out?
To create high area to volume ratios
-mycota is...
Fungi Phylum
-mycetes is...
Fungi Class
How do fungi reproduce?
Budding, fragmentation, and spores
What is sclerotium?
hardened mass of mycelium that serves as an overwintering stage
How is sclerotium formed?
excess hyphae take in extra water then dehydrate to form a "scab"

Chytridiomycota
What are benefits of Chytridiomycota?
It is important in the carbon cycle and helps control mosquitos
What are negatives to Chytridomycota?
It is detrimental to amphibians and parasitic to phytoplankton, humans, and animals
What fungi phyla grows rapidly, most diverse, and found in soil?
Zygomycota
What are the benefits of Zygomycota?
It is important in the carbon cycle, has a mutualistic relationship with plants, and insect control
What are negatives to Zygomycota?
it has pathogens to plants, animals, and amoeba, and targets fruits and breads
What fungi phyla produces their spores in sac-like structures, is single cellular(yeast), and found in most lichens?
Ascomycota
What are benefits of Ascomycota?
It is yeast, has a symbiotic relationship with plants, and insect control
What are negatives of Ascomycota?
It molds blue, green, and brown, Dutch Elms Disease, powdery mildew, parasitic, and causes fungal pneumonia
What fungi phyla is highly evolved, has long-lived dikaryotic mycleia, and is known as puffballs?
Basidiomycota
What are benefits of Basidiomycota?
It has pharmalogical uses, has edible varieties, and has a symbiotic relationship with conifers and hardwood
What are negatives of Basidiomycota?
It has plant and tree diseases(fairy ring) and leads to wood decay
Which fungi phyla is the newest, has an important role in horticulture, and causes mycorrhizae?
Glomeromycota
What are Lichens?
A symbiotic relationship between algae and fungi
What is mycorrhizae?
A mutualistic relationship between fungi and plants when the fungi grows on or around the roots and helps the plants intake water and nutrients
What is Ectomycorrhizae?
When fungi grows on the exterior of the plants root
What is Endomycorrizhae?
When fungi penetrates the plant roots
What was the first plant?
Similar to green algae because of photosynthesis a and b
What are Apical Meristems?
The growing points on a plant
Characteristics of Apical Meristems
It does not have storage, grows rapidly, recovers quickly, and cell walls are thinner
What are dependent embryos?
Embryos that stay in the parent plant until ready
What is alteration of genreation?
When both haploid and diploid cells are in the parent plant at the same time
What is the purpose of walled spores?
It allows it to hold moisture and nutrients, as well as protects it
Where would plants typically have a cuticle?
It would be in any extreme climate
What is antheridium?

What is archegonium?
It is a non-motile plant egg
What does it mean to be thallus?
No vascular tissue
What are rhizomes?
They function as shallow roots to anchor the plant
