Science Chapter six
| Question | Answer |
|---|---|
| The process of grouping things based on their similarities. | Classification |
| The scientific study of how living things are classified. | Taxonomy |
| The naming system for organisms in which each organism is given a two-part name—a genus name and a species name. | Binomial Nomenclature |
| A classification grouping that consists of a number of similar, closely related species. | Genus |
| A group of similar organisms whose members can mate with one another and produce fertile offspring. | Species |
| A series of paired statements that describe the physical characteristics of different organisms. | Taxonomic/Dichotomous Key |
| Microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes | Archaebacteria |
| A bacterium of a large group typically having simple cells with rigid cell walls and often flagella for movement. The group comprises the “true” bacteria and cyanobacteria, as distinct from archaebacteria | Eubacteria |
| free-living or colonial organisms with diverse nutritional and reproductive modes. | Protist |
| Any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools | Fungi |
| Autotrophic producers | Plants |
| A long, whiplike structure that helps a unicellular organism move. | Flagellum |
| A form of asexual reproduction in which one cell divides to form two identical cells. | Binary Fission |
| The reproductive process that involves only one parent and produces offspring that are identical to the parent. | Asexual Reproduction |
| The reproductive process that involves two parents who combine their genetic material to produce a new organism, which differs from both parents. | Sexual Reproduction |
| The process in which a unicellular organism transfers some of its genetic material to another unicellular organism. | Conjugation |
| A small, rounded, thick-walled, resting cell that forms inside a bacterial cell. | Endospore |
| A disease that can pass from one organism to another. | Infectious Disease |
| A poison that can harm an organism. | Toxin |
| A chemical that kills bacteria or slows their growth without harming the body cells of humans. | Antibiotic |
| A dog, a flea on the dog’s ear, and a rabbit the dog chases have much in common. All animals are multicellular eukaryotes. | Animal |
