Classification
The science of naming organisms and assigning them to groups called taxon
Taxonomy
The two kingdoms of prokaryotes
Bacteria and Archaea
The four kingdoms of Eukaryotes
Protists, Fungi, Plants, Animals
Viruses must attach to a host cell because they are
parasitic
An epidemic that has spread globally
Pandemic
What are the 7 level of classification in order from largest to smallest?
kingdom, phylum, class, order, family, genus, species
A rod-shaped bacteria arranged in chains
Streptobaccilli
Animals without a backbone
Invertebrates
The virus that infects only bacteria
bacteriophage
Organisms that do not have a true nucleus or membrane bound organelles
Prokaryotes
This is used to place organisms into a classification group by giving two choices for each characteristic with a unique ending for each organism
dichotomous keys
Bacteria can be autotrophic or heterotrophic. This kind of bacteria assemble complex carbon molecules from simple inorganic chemicals
Autotrophic
The bodies of most fungi are mesh-like, composed of a branching network of filaments called
mycellium
The only characteristic that viruses share with other living organisms
genetic information
A relationship where both organisms help each other
symbiotic relationship
The formal system for naming species where they are assigned a genus name and a specific name
binomial nomenclature
Bacteria reproduce asexually through
binary fission
Male gametes are carried from one plant to another by wind or other animals through a process called
Pollination
A very small infectious piece of RNA responsible for some serious diseases in plants
Viroid
Sexual reproduction of unicellular protists
Conjugation
A taxonomic group that includes a single common ancestor and all its descendants
Clade
A small loop of DNA that usually carries a small number of genes
Plasmid
This kingdom is characterized as being mostly unicellular, eukaryotic, mainly reproducing asexually, and like moist surroundings
Protista
The life cycle when viral DNA destroys Cell DNA, takes over cell functions and destroys the cell
Lytic
A small opening in the epidermis of a plant that allows for gas exchange
stomata
