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 of 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 organisms three groups: archaea, bacteria, and eukarya |
domain bacteria | prokaryotic ,single-celled organism that lacks a nucleus in its cell this is our environment |
domain archea | prokaryotic , single-celled organisms that lacks a nucleus in its cell and can live in extreme enviroments |
domain eukarya | organisms with cells that contains a nucleus |
kingdom | a taxonomic rank below domain 6 groups: animilia, fungi, plantae, prosista, archea, and eubacteria |
autotroph | an organism that is able to make its own food;known |
heterotroph | an organism that is able to 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 |
sexual reproduction | 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 orginisms are made up 1 or more cells; cells are the basic unit of life and all cells come from other cells |
kingdom archeabacteria | unicellular, asexual, auto and heterotrioph, prokaryotic organisms that live in extreme environments |
kingdom eubacteria | unicellular , asexual, auto and heterotroph , prokaryotic organisms that live in moderate environments |
kingdom protista | uni- and multicellular cellular sexual |
