Alternation of generations
A process in which an organism switches between diploid and haploid forms with each generation.
Angiosperm
A plant that produces seeds with protective covers.
Animalia
The eukaryotic kingdom consisting of all animals.
(a)rchaea
The domain consisting of nonbacterial prokaryotes.
(A)rchaea
Members of the prokaryotic domain Archaea.
Bacteria
The domain consisting of all bacteria.
Chemical evolution
The idea that simple molecules can spontaneously combine to make more complex ones.
Cuticle
A waxy, airtight seal that covers plants and allows them to live on land.
Deuterostome
Animal, such as human or sea star, that is characterized by the particular way it's digestive system develops.
Domain
The largest category used to classify living organisms. There are three domains: Eurkarya Bacteria and Archaea
Endosymbiosis
A type of symbiosis("living together") in which one organism lives inside the body or cells of another.
Era
A phase of time identified by significant events and characteristics in Earth's history.
Eukarya
The domain consisting of all eukaryotes.
eukaryote
An organism consisting of one or more cells. Each cell contains a membrane-enclosed nucleus.
Fungi
spore-producing organisms that absorb nutrition by feeding on matter that was or is living
Gametophyte
The haploid form of an organism experiencing alternation of generations. through mitosis, gametophytes produce haploid gametes that join together and grow into sporophytes.
Gymnosperm
A plant that produces seeds without protective covers.
Kingdome
In taxonomy the grouping of organisms below domain and above phylum EX Animalia
Period
In a geologic timetable a phase of time within an era.
Plantae
The eukaryotic kingdom consisting of all plants.
Prokaryotes
A one-celled organism that does not have a membrane-enclosed nucleus.
Protist
A single celled eukaryotic organism that is a member of the kingdom Protista. Any organism that is not a plant, animal, or fungus is a protist EX: Amoeba
Protista
The Eukaryotic kingdom consisting of all protists.
Protobiont
A sac of nucleic acids and other molecules surrounded by a simple membrane. A precursor to the first cells.
Protostome
Animal, such as an insect or a worm, that is characterized by the particular way it's digestive system develops.
Sporophyte
The diploid form of an organism experiencing alternation of gernerations. Though meiosis, sporophytes produce haploid spores that grow into gametophytes.
Geologic time scale
A list of eras, period, or other denominations of time and the events that occurred in those times.
Vertebrate
