Bio 204 plant diversity
1. where do plants fit into the basic classification scheme of living things?: living
things are either plants or animals; plants are anything with a cell wall and/or photosynthesis
2. what are "natural" (monophyletic) groups of organisms?: genetically related evolution-
ary lines; bryophytes, seedless vascular plants, and seed plants
3. what are "artificial" (polyphyletic) groups of organisms?: many unrelated evolutionary
lines; the result of convergent evolution of traits; most fungi and algae
4. what are the main groups of fungi?: ABCGZ; 1) Ascomycota 2) Basidiomycota 3) Chytridiomycota
4) Glomeromycota 5) Zygomycota
5. What is the role of Ascomycota ?: Sac fungi, form antibiotics by producing penicillin
6. What is the role of Basidiomycota?: Basidium means "club" where it produces spores in their club
like structure, usually mushrooms
7. What is the role of Chytridiomycota?: Flagellated stage where they swim, main cause for frog
deaths
1/9
,8. What is the role of Glomeromycota?: Almost all plants have this symbiotic relationship; gives plants
increased surface area to take in more water, while giving a home to the fungi
9. What is the role of zygomycota?: Creates bread mold from releasing spores from sporangia
10. what are the basic growth forms of lichens?: Crustose, squamulose, folios, umbilicate, and
fruticose
11. What are the roles of lichens?: Cyanbacteria in lichen fixes atmospheric nitrogen, making it available
to plants; lichens break down rocks to help soil; food source for animals in areas where water i limited
12. What are the five main groups of algae?: 1) green algae (chlorophyta) 2) brown algae
(Phaeophyta) 3) red algae (Rhodophyta) 4) diatoms (chrysophyta) 5)euglenids (euglenophyta)
13. Are fungi parasitic?: Very few, most are saprophytic (lives on dead matter)
14. what does karyogamy mean?: fusion of the nuclei
15. What is autoecious?: One host; corn smut, produces spore and moves onto more corn
16. What is heteroecious?: 2 hosts, grows on host A then grows on host B once done it goes back to host A

, 17. Describe the basic evolution of land plants, from bryophytes to seedless
vascular plants to seed plants (gymnosperms, then angiosperms).: Bryophytes
moved to land first time, seedless vascular plants have tissues for water and nutrient transportation, gymnosperms have
their own seeds to produce more plants themselves, angiosperms have flowers that produce multiple seeds themselves
through insect pollination
