| Term | Definition |
|---|---|
| cell | the smallest unit of an organism that performs life functions |
| nucleus | a structure found in Eukaryotic cells that contain DNA and is responsible for controlling the activities for the cell |
| Eukaryotic | a cell containing a membrane -enclosed nucleus and organelles |
| Prokaryotic | a cell lacking a nucleus or any 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 organisms by their structure function and relationship |
| Domain | the highest and largest rank of grouping organism Three groups: Archaea ,Bacteria,and Eukarya |
| Domain Bacteria |
prokayotic,single-celled organism that lacks a nucleus in its cell |
| Domain Archaea |
prokayotic,single-celled organism that ;acks a nucleus in it cell and can live in 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;known as a producer in a food chain |
| heterotroph | an organism that cannot make it own food;known as a consumer in the food chain |
| asexual | a method of reproduction that requires only one parent source 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 Archea bacteria |
unicellular,asexual,auto and heterotroph,prokaryotic organism that live in extreme environments |
| kingdom Eubacteria |
unicellular,asexual,auto and heterotroph prokaryotic |
| kingdom Protista |
uni-and multi cellular sexual or asexual auto- or hetero trophic eukaryotic organism that are microscopic |
| Kingdom Fungi |
uni-and multicellular sexual or asexual hetero trophic ,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 |
mulicellular ,sexual,and asexual heterotrophs, eukaryotic organisms;known as a consumer in the food chain |
