| host | the organism that a parasite or virus lives in or on |
| nucleus | the control center of a eukaryotic cell that directs the cell's activities and contains the information that determines the cell's form and function |
| plantae | the kingdom that contains plants- complex, multi-cellular organisms that are usually green and use the sun's energy to make sugar by photosynthesis |
| dichotomous key | an aid to identifying unknown organisms that consists of several pairs of descriptive statements |
| binary fission | a form of asexual reproduction in which one cell divides to form two identical cells |
| taxonomy | the scientific study of how living things are classified |
| photosynthesis | the process in which some organisms use water along with sunlight and carbon dioxide to make their own food |
| heterotroph | an organism that cannot make its own food |
| archaebacteria | a classification kingdom that contains ancient bacteria that thrive in extreme environments |
| protista | a kingdom of eukaryotic, single-celled or simple mullti-cellular organisms, contains all eukaryotes that are not plants, not animals, and not fungi |
| genus | a group of organisms that are made up of two or more species that are very much alike |
| fungi | a eukaryotic organism that has cell walls, uses spores to reproduce and is a heterotroph that feeds by absorbing its food |
| offspring | the new organism produced by one or two parent organisms |
| asexual reproduction | the reproduction process that involves only one parent and produces offspring that are identical to the parent |
| sexual reproduction | a reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents |
| homeostasis | the maintenance of stable internal conditions in an organism |
| classification | the process of grouping things based on their similarities |
| animalia | the classification kingdom containing complex, multi-cellular organisms that lack cell walls, are usually able to move about, and possess nervous systems that help them be aware of and react to their surroundingsa form of asexual repro |
| parasite | the organism that benefits by living on or in a host in a parasitism interaction |
| prokaryote | an organism whose cells lack a nucleus and some other cell structures |
| cell wall | aa ridig layer of nonliving material that surrounds the cells of plants and some other organisms |
| cell | the basic unit of structure and function in living things |
| eubacteria | a classification kingdom containing mostly free-living bacteria found in many varied environments |
| species | a group of organisms that are physically similar and can mate with each other and produce offspring that can also mate and reproduce |
| consumer | an organism that obtains energy by feeding on other organisms |
| producer | an organism, such as a plant, that can make its own food |
| chloroplast | the structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food |
| autotroph | an organism that makes its own food |
| eukaryote | organisms with cells that have a nucleus |
| taxonomy | the scientific study of how things are classified |
