synthesis | the composition or combination of parts or elements so as to form a whole |
egestion | the act or process of discharging undigested or waste material from a cell or organism |
metabolism | the sum of the processes in the buildup and destruction of protoplasm |
organism | a complex structure of interdependent and subordinate elements whose relations and properties are largely determined by their function in the whole |
heterotrophic | requiring complex organic compounds of nitrogen and carbon (such as that obtained from plant or animal matter) for metabolic synthesis |
Eukaryote(s) | any of a domain (Eukarya) or a higher taxonomic group (Eukaryota) above the kingdom that includes organisms composed of one or more cells containing visibly evident nuclei and organelles |
Unicellular | having or consisting of a single cell |
Taxonomy | the study of the general principles of scientific classification |

Genus | a class, kind, or group marked by common characteristics or by one common characteristic |
Binomial nomenclature | a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself |
Autotrophic | requiring only carbon dioxide or carbonates as a source of carbon and a simple inorganic nitrogen compound for metabolic synthesis of organic molecules (such as glucose) |
regulation | involving or reproducing by reproductive processes (such as cell division, spore formation, fission or budding. |
kingdom | a politically organized community or major territorial unit having a monarchical form of government headed by a king or queen |
