100% Verified Answers
Q1: Excavata
A: PROTIST
Highly modified mitochondria
Multiple flagella
'excavated' feeding groove
cause numerous human diseases (Chagas disease, sleeping sickness, non-bacterial
gastroenteritis, STDs that increase HIV suceptability
Q2: Chromalveolata
A: PROTIST
Derived from secondary endosymbiosis of red algae
Dinoflagelates are main component of plankton: cause red tides, some of which
produce harmful neurotoxins or deplete O2 levels in water, photosynthesis
endosymbiotes of coral-temp rise causes coral bleaching, bioluminescent
Cause human diseases (malaria)
Diatoms contribute to almost 45% of ocean primary productivity, providing vast amounts
of energy and O2
Q3: Rhizaria
A: PROTIST
Amoeba like; threadlike pseudopodia
Parasites of plants and animals
Index fossils
Q4: Archaeplastida
A: PROTIST
Include red algae, green algae, and land plants
Help with reef formation
Edible (sushi wrap)
Q5: Unikonta
A: PROTIST
Amoebazoans; tubelike pseudopodia
Cause human diseases (brain-eating amoeba)
Q6: Microsporidia
A: FUNGI
Intracellular parasite
Polar tube-structure to gain entrance into host
Animal parasite causing chronic/debilitating diseases
,Q7: Chytridomycota
A: FUNGI
Flagellated spores/gametes contained in sporangium/gametangium
Cause of amphibian decline
Q8: Zygomycota
A: FUNGI
Sexual phase produces zygosporangium; persists for months in harsh environment
Make food go bad
Q9: Glomeromycota
A: FUNGI
Produces mutualistic mychorrhizae
90% of land plants have mycorrhizae
Humans may have never evolved without mycorrhizae facilitating plant land invasion
Q10: Ascomycota
A: FUNGI
Cup fungi
Sexual phase produces ascocarp
Truffles are yummy
Q11: Basidiomycota
A: FUNGI
Club fungi/mushrooms
Sexual phase produces basidiocarp
Gills lined with spores
Club fungi are yummy
Certain times contain psychoactive compounds
Q12: Bryophytes
A: PLANTS
Non-vascular/seedless
Gametophyte is dominant life stage
Possess antheridia and archegonia (male and female gametangia)
Sporophyte grows from archegonium
Reproduction water dependant (flagellated sperm)
Taxa: Liverworts, Hornworts, and Mosses
Q13: Vascular traits
A: PLANTS
Seedless or seed
Vascular tissue (Xylem and Phloem)
Sporophyte dominant
, Roots
Leaves (microphyll or megaphyll)
Sporophylls (Homosporus or Heterosporus)
Lycotphytes, Horsetails, and Whiptails
Q14: Seed traits
A: PLANTS
Reduced gametophyte stage
Heterospory
Ovules
Pollen
Gymnosperms or Angiosperms
Q15: Gymnosperms
A: PLANTS
Naked; ovule not surrounded by ovary or fruit
Phyla: Ginkophyta, Gnetophya, Cycadophyta, Coniferophyta
Q16: Ginkophyta
A: PLANTS (GYMNOSPERMS)
Only one species
Used in traditional medicine for circulatory disorders, memory enhancement and
dementia
Q17: Gnetophyta
A: PLANTS (GYMNOSPERMS)
Only gymnosperm to exhibit 'Double-fertilization'
Q18: Cycadophyta
A: PLANTS (GYMNOSPERMS)
Crown of stiff compound leaves with a short truck. Dominant tree during Mesozoic.
Often mistaken as "palms" which are angiosperms. Diocecious.
Q19: Coniferophyta
A: PLANTS (GYMNOSPERMS)
Examples are pine and fir trees (most are evergreen)
Most species rich gymnosperm
Q20: Angiosperm
A: PLANTS
Ovule surrounded by ovary or fruit; flowering plants
Flower structure: Stamen (male), Carpel (female), Petal and Sepal
