Unit 11 Science
Texonomic Groups
| Term | Definition |
|---|---|
| cell | the smallest unit of an organism that performs life functions |
| nucleus | a structure found in eukaryota 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 anything other membrane-enclosed organelles |
| unicellular | an organism made up of one single cell |
| multicellular | an organism made up of more than one cell,and often made up of different types of cells |
| classification | the process of grouping things based on similarities |
| taxonomy | the branch of science that formally names and classifies |
| Domain | the highest and largest rank of grouping organisms Three groups : Archaea,Bacteria,and Eukarya |
| Domain Bacteria | prokaryotic,single-celled organism that lacks a necleus in its cell |
| Domain Archaea | prokaryotic ,single-celled organism that lacks a nucleus in its cell and can live in extreme environments |
| Domain Eukarya | organisms with cells that contain a necleus |
| Kingdom | a taxonomic rank below Domain 6 groups: Animalia,Fungi,Platae,Protista,Archaea,and Eubacteria |
| autotroph | an organism that is able to make its own food,known as a producer in food chain |
| hetreotroph | an organism that CANNOT make its own food,known as a consumer in the food chain |
| asexual reproduction | a method of reproduction that requires only one parent 100% DNA from 1 parent |
| sexual reproduction | a method of reproduction that requires both male and female parent 50% from 1 parent and 50% from the other 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 Bacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in moderate environments |
| Kingdom Eubacteria | unicellular,asexual,auto and heterotroph,prokaryotic organisms that live in moderate enviroments |
| Kingdom Protista | uni- and multi cellular sexul 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 | multicellular,sexual and asexual,autotrophs,eukaryotic organism;known as a producer in the food chain |
| Kingdom Animilia | multicellular,sexual and asexual,heterotrophs,eukaryotic organisms;known as a consumer in the food chain |
