What's That Species
A researcher is out searching for a specific organism known for its filamentous growth and thick cell walls. They must use caution cause even though they intend on developing an antibiotic this organism can cause tuberculosis.
Actinobacteria (Mycobacterium tuberculosis) (Lecture 12, slide 35)
The term "Prokaryotes" refers to
Bacteria and Archaea
all life forms (6 traits shared by all life; Lecture 11, slide 29)
The human life cycle is
diplontic (Lecture 14, slide 6)
Adaptations made by ALL land plants
Embryophytic and cuticle (Shows challenges and adaptations for land plants; Lecture 14, slides 4&5)
The organism located growing on a damp trail is known as the most primitive tracheophyte
Lycophytes or club moss **microphylls - leaves w/o vasculature (Lecture 14, slide 35)
The three groups of archaea are
Lokiarchaeota, crenarchaeota, and Euryarchaeota (Lecture 11, slide 18)
The five important facts about seed plants
seeds allow dormancy, seeds allow dispersal, all heterosporous, dramatic reduction gametophytic phase, and sporophyte dominant (Lecture 15, slide 12)
The two "phases" of haplodiplontic lifecycle
Gametophyte (multicellular haploid), Sporophyte (multicellular diploid) **haploid phase gets shorter as plants evolve
The tissue layers in triploblastic animals
Ectoderm (outer body covering), Mesoderm (skeletal muscle), Endoderm (digestive organs intestines) **Mesoderm absent in diploblastic animals (Lecture 18, slide 9)
During the dissection of an unidentified organism it is found to possess distinctive organ systems. With further analysis it is also confirmed to have nerve nets
Cnidarians (Lecture 18, slide 11)
The presence of peptidoglycan guarantees we are looking at
a bacteria (archaea will NEVER have peptidoglycan, Lecture 12)
The universal body plan of mollusks includes
Visceral mass, foot, mantle (Lecture 19, slide 4)
gametophyte dominant **Bryophytes are non-seed land plants (Lecture 14, slide 22)
The bacteria type obtains energy from the sun and carbon from organic compounds
Photoheterotroph (Metabolism table; Lecture 12, slide 21)
A scientist observes a observes a unicellular organism glowing on the shore at night. They bring a sample back to their lab and learn the organism has alveoli and two flagella
Alveolate - Dinoflagellates (Lecture 13, slide 22)
The organism observed has unbranched lipids, this guarantees what
the organism is not an archaea (features of the tree of life; Lecture 12, slide 29)
grasping fingers and toes, binocular vision (Lecture 23, slide 27)
The defining difference between homosporous and heterosporous life cycles
homosporous cycles have generic gametophyte, heterosporous have specific male and female gametophytes (Lecture 15, slides 4&5)
The three types of chlorophyll and how they came to be
Chlorophyll a: primary endosymbiosis of cyanobacteria (chloroplasts)
Chlorophyll b: derived trait of green algae and land plants
Chlorophyll c: secondary endosymbiosis of red algae (brown algae)
(Lecture 14, slide 15)
A species is observed to posses hundreds of ball and socket joints
Sea Urchins **incredibly niche, not enough info for this to be an exam question (Lecture 20, slide 16)
The processes for cell division and gene transfer in "prokaryotes" and Eukaryotes are
"prokaryotes" binary fission and lateral transfer, eukaryotes mitosis and recombination (Lecture 12, slide 5)
The group is known for being unicellular, aquatic, and possessing thin rigid pseudopodia
Rhizarians (Lecture 13, slide 30)
The state of fungi that is neither haploid or diploid in its sexual reproductive cycle
dikaryotic (n+n) **plasmogamy and Karyogamy (Lecture 17, slide 13)
The four virus types and corresponding structures
Helical capsid (plant), Icosahedral capsid (animal adenovirus), Icosahedral head w/ tail (bacteria), and helical capsid w/ envelope (animal influenza) (Lecture 11, slide 4)
