Bacteria
Stain pink, thin layer of peptidoglycan, and more structurally complex.
What is Gram-Negative Bacteria?
Share some traits with bacteria and other traits with eukaryotes. Include a group called extremeophiles.
What is Unique About Archaea?
Rhizarians, Stramenopiles, Alveolates
What is Supergroup: SAR?
Ancestral population from which all the other species originate. (Think parts of a phylogenetic tree)
What is Root?
Causes stomach ulcers and was proved to do this by Barry Marshall.
What is Helicobacter pylori?
Only takes a small amount of oxygen (too much oxygen is toxic).
What is Microaerophile?
One organism benefits while the other is not harmed or helped.
What is Commensalism?
Two nuclei + Multiple Flagella. Use Mitosomes to generate energy
What is Giardia? (Diplomonad Protist)
The science of figuring out relationships between organisms.
What is Systematics?
Causes cholera, a bacterial disease causing severe diarrhea and dehydration, usually spread in water.
One characteristic that is only found in the Domain Bacteria.
What is Peptidoglycan (in cell wall)?
Live in highly saline environments and some require an environment that is several times saltier than seawater. (Ex: Halobacterium)
What is Extreme Halophiles?
Lack flagellated gametes and have to rely on water currents for fertilization.
Similarity due to convergent evolution (ex: Butterfly and bat wings)
What is Analogy?
Pathogen infects ticks, ticks bite people, and people end up getting Lyme Disease.
What is Borrelia burgdorferi?
What are Autotrophs?
Some prokaryotes can use this hairlike structure to stick to their substrate or to one another (Think of it like Velcro)
What is Fimbriae?
Multicellular, simple leaf-like body. Have blade and holdfast structures.
What is Ulva?
A shared derived trait that two or more groups have because they inherited it from a recent common ancestor (ex: mammary glands in mammals).
What is Synapomorphy?
Transmitted by tsetse flies in Africa. Immune evading defense tactic called “bait-and-switch”. Can cause African sleeping sickness and Chaga’s disease.
What is Trypanosoma?
DNA is transferred between two prokaryotic cels (usually the same species) that are temporarily joined via pili.
What is Conjugation?
Chemoheterotrophic prokaryotes that unlock supplies of carbon, nitrogen, and other elements.
What are Decomposers?
Exist as individual amoeboid cells when food is abundant and when food is scarce, cells aggregate into multicellular-like structure. Form a fruiting body.
What is Cellular Slime Molds?
Lineage, line, or clade that diverged earlier.
Requires two hosts: humans + mosquitoes (both asexual and sexual). Parasite infects mosquitoes and cause malaria in humans.
What is Plasmoidium?
