Classification
| Question | Answer |
|---|---|
| organism | any individual living system or being that can carry out life functions independently |
| cell | cell is the smallest, basic unit of life that makes up all living organisms and performs all life processes. |
| unicelluar | Unicellular means consisting of or having only a single cell. |
| multiceller | an organism is composed of more than one cell, rather than just a single cell |
| stimulus | stimuli) is any object, event, or change in the environment that causes a functional reaction, activity, or response from a living organism, a person, or an economic system |
| response | response is a spoken or written answer, or a reaction to an action, event, or physical stimulus. |
| development | the general process of growing, changing, or advancing to a more mature, complex, or advanced stage |
| asexual reproduction | a type of reproduction where a single parent creates offspring without the fusion of sex cells or gametes. |
| sexual reproduction | a biological process where a male and a female parent combine their specialized reproductive cells—called gametes (sperm and egg)—to create a genetically unique offspring |
| spontaneous | happening naturally or doing something without any prior planning or external pressure. |
| autotroph | an organism that creates its own food from simple inorganic substances using light or chemical energy |
| hetertroph | an organism that cannot make its own food and must get its energy and nutrients by consuming other living or dead organisms |
| classification | the general process of arranging objects, data, or organisms into pre-existing groups or categories based on shared characteristics |
| taxnomy | the science of naming, describing, and classifying organisms and other entities into structured, hierarchical groups. |
| binomial nomenclature | Binomial nomenclature is a universal two-part naming system used in taxonomy to give every species a unique scientific name. |
| Genus | when unrelated species independently evolve similar physical features or behaviors because they live in similar environments or face identical ecological pressures.Key Concepts |
| Species | A species is the basic unit of biological classification and a group of organisms that can interbreed to produce fertile offspring |
| Prokaryote | A prokaryote is a single-celling living thing that does not have a true nucleus or other parts wrapped in membranes |
| Eukaryote | A eukaryote is any organism made of cells that contain a membrane-bound nucleus and other specialized, internal compartments called organelles |
| Nucleus | cell that stores genetic material and directs cellular activities. |
| Evolution | the change in the inherited traits of a biological population over successive generations |
| Branching tree diagram | a visual tool that starts at a single point and splits into multiple paths to show relationships, choices, or outcomes. |
| Shared derived characteristics | a trait that two or more groups share because it evolved in their immediate common ancestor, but it is not found in more distant ancestors |
| Convergent evolution | the independent development of similar physical traits or body plans in unrelated species facing similar environmental pressures. |
