Domains and kingdoms Flashcards
(31 cards)
What are the 3 domains
Bacteria, Archaea and Eukarya
What are the 6 kingdoms
Eubacteria, Archaebacteria, Protista, Plantae, Fungi, Animalia.
What is the highest taxonomic rank
Domain
Which kingdoms are all Multicellular and Eukaryotic
which kingdom is eukaryotic but unicellular
Plantae, Animalia and Fungi
Protista
Which kingdoms are unicellular and prokaryotic
Eubacteria and Archaea
What the difference between Eukaryotic cell and prokaryotic
Eukaryotic - larger more complex cell -has a nucleus -numerous organelles Prokaryotic -tiny simple cell -no true nucleus -has ribsombes but no mb bound organelles.
What the difference between autotrophs and heterotrophs -
autotrophs make thier own foods like plants
heterotrophs cant make thier own food and must other organisms
Which kingdoms have no cell wall
Animalia and Protista
Which kingdoms have cells walls but are multi cellular
plantae and fungi
Which kingdoms have cells walls and are unicellular
Archaebacteria and Eubacteria
What is taxonomy
Science of classifying organisms (both living & extinct)
What is the purpose of taxonomy
- to identify organisms
2. to represent evolutionary relationships among them
Who developed the taxonomy system and what did he base it off of
Carl Linnaeus based it off of structural and physical features/ the more features in common.
What is binomial nomenclature
The scientific name of a species formed by the combination of
- Genus- (always chaptalised)
- Species
What is each level of classification called
Taxa
Name the levels of classifications in order
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
What is Phylogeny
Evolutionary history of species
What is phylogenical tree
diagram that illustrates the evolutionary
relationships between organisms
What are tips nodes and base in phylogenical tree
tips represnt series
node represents common ancestor
How are phylogenies determined
strucutural (morphology)
Development (embryology)
DNA (molecular genes)
Organisms likely share common ancestry if they…
- have similar autonomically structures, regardless of function.
- show similar stages of embryological development
- are genetically similar.
What is natural section
A mechanism for change in populations that occurs when organisms with favourable variations for a particular environment survive, reproduce, and pass on these variations on to the next generation.
What is artificual selection
human artificially selecting organisms for desirable traits.
What is Speciation
Divergent evolution that results in new species- think of the bears
