questions and answers passed
taxonomy - correct answer ✔✔the science of identifying and classifying all organisms
phylogenetic tree - correct answer ✔✔diagram showing how living organisms are related
the tree domains of life (phylogenetic categories) - correct answer ✔✔1. bacteria
2. archaea
3. eukaryote
what are animals most closely related to? - correct answer ✔✔fungi (650-99Ma)
hypo thermophiles - correct answer ✔✔organisms that live at very high temperatures
the five kingdoms - correct answer ✔✔1. bacteria (eubacteria, archaea)
2. plants
3. animals
4. fungi
5. protists
prokaryotic - correct answer ✔✔- unicellular
- no membrane-bound organelles
- domain: bacteria and archaea
,eukaryotic - correct answer ✔✔- unicellular or small multicellular
- has organelles
- domain: eukarya
clade - correct answer ✔✔a group of organisms consisting of a common ancestor and all of its
decendants
Taxonomy categories - correct answer ✔✔1. kingdom (least specific)
2. phylum
3. class
4. order
5. family
6. genus
7. species (most specific)
binomial nomenclature - correct answer ✔✔- organisms named by their genus and species
- genus starts with upper case
- species start with lower case
- italicized or underlined
Kingdom: bacteria (monerans) - correct answer ✔✔- unicellular
- prokaryotes
- single chromosome
- 2 groups: archaeans and bacteria
, Kingdom: Fungi - correct answer ✔✔- eukaryotic
- heterotrophs
- cell walls
- decompose dead organisms
heterotrophs - correct answer ✔✔organisms that have to eat other organisms to get energy
Kingdom: Plants - correct answer ✔✔- multicellular
- eukaryotic
- autotrophs
- cell walls
- use photosynthesis
autotrophs - correct answer ✔✔organisms that create their own food/energy
- ex: photosynthesis, chemoautotrophy
Kingdom: Protists - correct answer ✔✔- wide variety of eukaryotes
- everything that doesn't fit into the other kingdoms
convergent evolutio - correct answer ✔✔causes relatively unrelated organisms to become
related due to the demands of their ecological niche
Domain: archaea - correct answer ✔✔- bacteria
- grow in extreme environments
- first organisms
- produce O2 as waste
