| Term | Definition |
| Kingdom Prokaryotae | also called Monera, most primitive organisms on earth. single-celled prokaryotic cells. most commen are bacteria. some photosynthetic, chemosynthetic, or heterotrophic. |
| chemosynthetic | oxidize chemicals for energy |
| Kingdom protoctista | (Protista) most are single-celled eukaryotes. examples include paramecium, amoeba, and algea are multicellular examples |
| Kingdom Fungi | multicellular, except yeast. cannot move, get food from dead (if saphotrophs), or living (parisitic) |
| sessile | stagnant, cannot move |
| Kingdom plantae | multicellular organisms. eukaryotic cells. Sessile. producers, have specialized tissues, angiosperms are winners |
| Animalia | multicellular, capable of movement, specialized tissues, heterotrophs |
| Eubacteria | "true" bacteria domain of Kingdom Prokaryotae, numerous species found in soil, water, air, and organisms. few are pathogenic if in organisms, mostly mutualistic, or parisitic |
| Archea | "ancient group" domain of Prokaryotae. have several genetic/ structural differences between themselves and eubacteria. most live in extreme environments |
| Eukarya | domain name used for all organisms with eukaryotic cells (kingdoms protoctista, fungi, plantae, and animalia) |
| Protosomes | grouping of kingdom animalia, based on embryonic development patterns. "lower evolved", characterized by first embryonic opening (blastopore) becoming animal's mouth |
| Deuterostomes | embryonic grouping of animalia, where during development, the blastopore becomes the anus with the second opening becoming the mouth. |
| protosome animal phyla | Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda |
| deuterostome animal phyla | Echinodermata, Chordata |
| Acoelomates | grouping that only applies to animalia. no body cavity. example: phylum platyhelminthes flatworms |
| Pseudocoelomates | False body cavity, nematoda roundworms |
| Coelomates | true body cavity, example chordata |
| determinant cleavage | when cells have a decided "fate" when they are developed. occurs in protosomes |
| indeterminant cleavage | in deuterostomes, where cell's fate is decided later in development. stem cells |
