| organism | anything that has all of the characterisitcs of life (living and extinct things) |
| classification | the act of organizing things into groups, according to similarities |
| dichotomous key | a set of rules scientgist use to help classify organisms. It also is a tool for identifying unknown organisms. |
| Scientific name | two Latin words (Capitalize first word) used to name an organism; it is the Genus followed by species name |
| taxonomy | the science of classifying living and extinct organisms |
| Binomial Nomenclature | two names - Genus, Species |
| prokaryotes | cells without nucleus |
| classification | The division of organisms into groups and classes based on characteristics |
| species | The smallest, most specific classification level |
| prokaryotes | Single-celled organisms that do not have a nucleus. |
| protista | Kingdom that includes mostly single-celled or simple mutlicellular organisms |
| fungi | This kingdom includes non-green, non-moving Eukaryotic organisms that break down substances outside their bodies and absorb the nutrients |
| eukaryotes | All organisms whose cells have a nucleus and membrane bound organelles. |
| species | A group of organisms that are closely related and can mate to produce fertile offspring |
| sessile | fixed in one place, not mobile |
| plants | This kingdom includes complex, multi-cellular organisms that are usually green, have cell walls, and make sugar by photosynthesis. |
| animal | This kingdom includes complex, multi-cellular organisms that lack cell walls, can usually move and respond to their environment. |
| class | The level of hierarchy just below phylum is |
| taxonomy | Science of Grouping organisms according to their characteristics and evolutionary history |
| species | The lowest and most specific hierarchy level in biological classification |
| Kingdom Archaebacteria | 1. Unicellular (one cell) 2. Prokaryotic (no nucleus) 3. Archaic (Ancient or old) 4. Extremophiles (live in harsh conditions) |
| Kingdom Protista | kingdom composed of microscopic eukaryotes that are not classified as plants, animals, or fungi. |
| class | Kingdoms are divided into phyla, and a phylum is divided into |
| Kingdom Plantae | 1. Multicellular (many cells) 2. Eukaryotic (cells have a nucleus) 3. Autotrophic (photosynthesis) 4. Cell walls made of CELLULOSE |
| Genus | Group of closely related species, and the first part of the scientific name in binomial nomenclature |
| Kingdom Animalia | 1. Multicellular (many cells) 2. Eukaryotic (cells have a nucleus) 3. Heterotrophs (eat their food-consumers) 4. No cell walls |
| Homo sapiens | The scientific name for humans. -should be italicized or underlined |
| Kingdom Eubacteria | 1. Unicellular (one cell) 2. Prokaryotic (no nucleus) 3. Cause disease (like salmonella or E.coli) 4. Can be helpful (decompose, digest, make yogurt) |
| Kingdom, phylum, classes, order, families, genus, and species | What are the seven levels of classification from broad to specific? |
| Archaebacteria, Eubacteria, Protists, Fungi, Plantae, and Animalia. | Names of the 6 kingdoms |
| Plantae and Animalia | These kingdoms are multicellular |
| Archaebacteria and Eubacteria | These kingdoms are unicellular |
| Protists, Fungi, Plantae, and Animalia | These kingdoms are eukaryotic |
| Protists and Fungi | These kingdoms are both unicellular and multicellular |
| Archaebacteria and Eubacteria | These kingdoms are prokaryotic |
| autotrophic | organisms that make their own food |
| heterotrophic | organisms that get food from other sources |
| morphology | the branch of biology that deals with the form of living organisms, and with functions between their structures. |
| phylogeny | study of relationships among different groups of organisms and their evolutionary development |
| dichotomous key | guide for the classification and identification of a living organism. |
| two | Dichotomous keys always give _______ distinct choices in each step. |
| biosphere | the regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms. |
| scientific name | 2 parts composed of genus and species |
| binomial nomenclature | also known as scientific name |
