Taxonomic groups
| Question | Answer |
|---|---|
| cell | the smallest unit of an organism that preforms life functions |
| nucleus | a structure found in Eukaryotic cells that contain DNA and is responsible for controlling the activities of the cell |
| Eukaryotic | a cell containing a membrane - enclosed nucleus and organelles |
| Prokaryotic | a cell lacking a nucleus or any other membrane - enclose organelles |
| unicellular | an organism made up of one single cell |
| multicellular | an organism made up of one single cell, and often made up o different types of cells |
| classification | the process of grouping things based on similarities |
| taxonomy | the branch of science that formally names and classifies organisms by their structure, function and relationship |
| domain | the highest and largest rank of grouping organisms three groups: Archaea , bacteria, and Eukarya |
| domain bacteria | Prokaryotic, single celled organism that lacks a nucleus in its cell |
| domain Archaea | prokaryotic, single celled organism that lacks a nucleus in its cell and can live in extreme extreme environments |
| domain Eukarya | organisms with cells that contain a nucleus |
| kingdom | a taxonomic rank below domain 6 groups: animalia, fungi, plantae, protista, archaea, and eubacteria |
| autotroph | an organism that is able to make its own food food; known as a producer in food chain |
| heterotroph | an organism that cannot make its own food; known as a consumer in the food chain |
| asexual | a method of reproduction that requires only one parent 100% DNA from 1 parent |
| sexual | a method of reproduction that requires both male and female parent 50%from 1 parent 50 % from 1 parent |
| cell theory | states that all living organisms are made up of 1 or more cells; cells are the basic unit of life and all cells come from other cells |
| kingdom Archeabacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
| kingdom Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
| kingdom Protista | uni- and multi cellular sexual or asexual auto- and heterotrophic Eukaryotic organism that are microscopic |
| kingdom Fungi | uni- and multi cellular sexual or asexual, heterotrophic Eukaryotic organism known as a decomposer in the food chain |
| kingdom Plantae | multi cellular, sexual and asexual, autotrophs, eukaryotic organism; known as a producer in the food chain |
| kingdom Animilia | multi cellular, sexual and asexual, heterotrophs, eukaryotic organisms; known as a consumer in the food chain |
