Classification Flashcards
What is the Biological Species Concept?
a species contains all organisms that are capable of breeding together to produce living, fertile of spring.
What is the classification?
the process of sorting living things into groups
Classifi cation hierarchy comprises the taxa…
domain, kingdom, phylum, class, order, family, genus species.
Methords to infer relationships in classification
physical characteristics to DNA sequencing, amino acid sequencing or cytochrome C comparisons.
What are the 5 kingdoms?
Animalia Plantae fungi and Protista and prokaryote
Describe the animalia kingdom?
Animals are eukaryotic, multicellular, heterotrophic and usually able to move around
Describe the plantae kingdom
Plants are eukaryotic, autotrophic, multicellular, have a cellulose cell wall, and contain chlorophyll
Describe the kingdom fungi
Fungi are eukaryotic, single-celled or multicellular, saprophytic, have a chitin cell wall and a multinucleate cytoplasm
Describe the protoctista kingdom
Protoctists are eukaryotic, mostly free living, single-celled or multicellular, autotrophic or heterotrophic,
Describe the prokaryoate kingdom
Prokaryotes have smaller ribosomes, a naked loop of DNA, free living or parasitic, no nucleus or no other membrane bound organelles,
What is the binomial naming system
names species by their genus and species name
What is Phylogeny?
the study of evolutionary relationships between organisms.

Describe branch tips of a phylogenetic diagram
branch tips represent species at the end of their specific lineage,
Describe branching points of a phylogenetic diagram
branching points represent common ancestors & The closer the branches, the closer the evolutionary relationship
