Taxonomy
What is binomial nomenclature?
This system of naming organisms uses two Latin names. Genus and Species
What are gram-positive bacteria?
Bacteria that stain purple. Usually harmless species.
What are eukaryotic cells
Cells that have membranes (inside too). Protists start here!
What are invertebrates?
Animals without backbone are classified as this group
What are bryophytes?
Nonvascular plants (mosses, liverworts)
Who is Carolus Linnaeus?
"Father of Taxonomy"
The three basic shapes of bacteria:
2. Cocci
3. Spirilla
Amoeba move around using fake protein projections called...
Pseudopods
What is bilateral symmetry?
Symmetry split across one axis. These organisms have head region
What is a xylem?
Found in vascular plants, tube tissue that transports water/minerals
The seven taxonomic ranks are...
Kingdom, Phylum, Class, Order, Family, Genus, Species
The process that allows bacteria to 'share' plasmids
1. Conjugation
2.Transformation
Plant-like protist that can photosynthesize in light but are hetertophic too
Euglena
What is a body cavity referred to as?
Coelom
What are the two cell types found in sexual reproduction called? Explain the difference
Haploid + Diploid
Which taxonomic level will be most specific and considers the greatest diversity?
Species
Bacteria that need oxygen to survive
Obligate aerobes
Fungi absorb nutrients using threadlike structures called...
hyphae
What are features of birds
1. hollow bones
2. feathers
4. four chmabered hearts
5. endotherms
What are two things Viruses lack that living cells can do?
Cell strutures (lipids, membranes)
independent reproduction (without a host)
What is a defining features of the (most) Chordata phylum?
Notochord
Major reason for antibiotic resistance
Misuse of antiobiotic prescription
Mutualistic relationship between fungi and plants happens through what? Give an example of symbiotic relationship
Mycorrhiza
Evolutionary adaption that allowed marine organisms to reproduce on land without returning to water
Amniotic egg
Explain the lysogenic cycle
Viral DNA integrates into host genome and can remain unsymptomatic for years
HIV is an example virus.
