Term | Definition |
---|---|
Animalia | kingdom of multicellular eukaryotic heterotrophs whose cells do not have cell walls |
Archaebacteria | kingdom of unicellular prokaryotes that have cell walls |
Domain | largest grouping in the classification of organisms, above kingdom |
Eubacteria | kingdom of unicellular prokaryotes that have cell walls |
Fungi | kingdom composed of heterotrophs; many obtain energy and nutrients from dead organic matter |
Kingdom | second largest grouping in organism classification, as in the animal kingdom |
Plantae | kingdom of multicellular photosynthetic autotrophs that have cell walls |
Protista | kingdom composed of eukaryotes that are not classified as plants, animals, or fungi |
Taxonomic | classification of organisms |
Asexual | A term describing reproduction that does not involve gene transfer between parent cells. |
Autotroph | an organism that can produce its own food using light, water, carbon dioxide, or other chemicals |
Ecosystem | a geographic area where plants, animals, and other organisms, as well as weather and landscapes |
Eukaryote | any cell or organism that possesses a clearly defined nucleus. |
Heterotroph | an organism that eats other plants or animals for energy and nutrients. |
Multicellular | many cells |
Prokaryote | organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes |
Sexual | the mixing of genetic material. The term reproduction means to produce another offspring. These terms together mean the production of another offspring by means of mixing genetic material. |
Species | a group of organisms that can reproduce with one another in nature and produce fertile offspring. |
Unicellular | made of only one cell |
