Term | Definition |
Cell | the smallest unit of an organism that performs life functions |
nucleus | a structure found in eukaryotic cells that contain DNA |
eukaryotic | a cell containing a membrane- enclosed nucleus and organelles |
prokaryotic | a cell lacking a nucleus or any other membrane enclosed organellas |
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 organism by there structure function and relationship |
domain | the highest and largest rank of grouping organisms three groups Archae bacteria and eukarya |
domain bacteria | prokaryotic, single celled organism that lacks a nucleus in its cells |
domain archaea | prokaryotic , single celled organism that lacks a nucleus in its cell and can live in extreme environments |
domain eukarya | organism with cells that contain a nucleus |
kingdom | a taxonomic rank below domain |
autotroph | an organism that is able to make its own food; known as a producer in the food chain |
heterotroph | 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 and 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, prokayotic organism that live in moderate environments |
kingdom protista | uni- and multicellular sexual or asexual auto- and heterothopic eukaryotic organism that are microscopic |
