taxonomy/cladogram
Picture vocab
| Term | Definition |
|---|---|
| Binomial Nomenclature | The system of naming organisms scientifically, developed by carolus Linnaeus; consists of the genus and species names. |
| Kingdom | The highest level of taxonomic classification beneath that of the three domains. |
| Phylum | the taxonomic level below kingdom and above class |
| Class | The taxonomic level below phylum and above order |
| Order | the taxonomic level below class and above family |
| Family | The taxonomic level below order and above genus |
| Genus | The taxonomic level below the family and above the species; the first part of the binomial nominclature |
| Species | A group of organisms that can interbreed to generate fertile offspring. |
| Cladogram | A branching diagram representing a hypothesis about the evolutionary descent of groups of organisms from a common ancestor |
| Dichotomous Key | A tool used to classify an organism through a series of questions with only two possible answers. |
| Ancestry | The lineage of successive parents and offspring that leads to an organism or species. |
| Cladistics | A classification system based on shared characteristics between groups of organisms and their common ancestor. |
| unicellular | Composed of a single cell |
| Multicellular | Composed of more than one cell |
| Heterotrophic | An organism that must consume other organisms for energy |
| Autotrophic | An organism that obtains its energy from an abiotic source such as sunlight or inorganic chemicals. |
| Chemotrophic | An organism that can produce its own nourishment through the process of oxidizing inorganic compounds |
| eukaryotic Cell | A cell with a nucleus and membrane-bound organelles |
| prokaryotic Cell | A cell lacking a nucleus or any other membrane-enclosed organelle |
| Sexual Reproduction | The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves |
| Asexual Reproduction | A method of reproduction that requires only one parent and produces offspring identical to the parent |
| Phylogeny | The evolutionary development of a species |
| four kingdoms of eukaryotes | Protista, plantae, fungi, and animalia |
| Protista | Many are unicellular, classified in this kingdom because they do not fit others. |
| Plantae | Plants, multicellular organism that are able to photosynthesize. |
| Fungi | mostly Multicellular, cell wall, cannot photosynthesize. |
| Animalia | Includes humans, multicellular, heterotrophic, no cell wall. Mobile at least some point in life. |
| Taxonomist | Scientists who study taxonomy and use the classification system to identify and name organisms. |
| Domains | Bacteria, archaea, Eukarya |
| Domain Bacteria | unicellular prokaryotes nucleus/membrane bound organelles |
| Domain Eukarya | Very diverse, divided into four kingdoms |
| Domain Archaea | Unicellular prokaryotes, have a cell wall, but different in composition from bacteria, Lack peptidoglycan. able to survive in some of the most extreme places on Earth. |
