The science of describing, naming, and classifying organisms.
The analysis of evolution, or ancestral, relationships between taxa.
Devised a system of grouping organisms into hierarchal categories according to their form and structure.
The transfer of a bacterial gene from one bacterium to another through a bacteriophage.
What genus are homo sapiens a member of?
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What is the correct order of biological hierarchy?
A kingdom made up of complex, multicellular organisms that lack cell walls, are usually able to move around, and possess specialized sense organs that help them quickly respond to their environment.
A kingdom that contains all prokaryotes except Archaea.
A kingdom made up of nongreen, eukaryotic organisms that get food by breaking down organic matter and absorbing the nutrients, reproduce by means of spores, and have no means of movement.
A kingdom made up of eukaryotic, multicellular organisms that have cell walls mostly of cellulose, that have pigments that absorb light, and that supply energy and oxygen to themselves and to other life-forms through photosynthesis.
Animalia, Eubacteria, Fungi, Plantae
What are the four kingdoms?
Archaea, Bacteria, Eukarya
What are the three domains?
A domain made up of prokaryotes that can live in extreme environments and that are differentiated from other prokaryotes by various important chemical differences.
A domain made up of prokaryotes that usually have a cell wall and that usually reproduce by cell division.
A domain made up of all eukaryotes.
What color do Gram-positive bacteria stain?
Because of their cell wall
Why do Gram-positive bacteria retain their color after staining?
None of their own cells, have to use host cells, no metabolism
What are three reasons viruses are considered non-living?
A nucleic acid and a protein coat
What two substances make up a virus?
If they have RNA or DNA
How are viruses classified?
Viruses that contain RNA.
Similar to a virus, but without a genome; is basically just an infectious protein.
They are non-living
Why don't antibiotics work on viruses?
A type of bacteria that supplies nitrogen to plants.
The smallest known particle able to replicate.
