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 organelles |
prokaryotic |
a cell lacking nucleus or any other membrane – enclosed organelles |
unicelluar |
an organism made up of one single cell |
multicelluar |
an organism made up of more than one cell, and often made up of different types of cells |
classification |
the process 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
|
Domain Bacteria |
prokaryotic single- celled organism that lacks nucleus in its cell |
Domain Archaea |
prokaryotic, single – celled organism that lacks nucleus in its cell and can live in extreme enviroments |
Domain Eukarya |
organisms with cells that contain a nucleus |
Kingdom |
a taxonomic rank below Domain 6 Groups: Animalia, Fungi, Plantae, Archaea, and Eubacteria
|
autotroph |
an organism that is able to make its own food; known as a producer in food chain |
heterotroph |
an organism that CANNOT make its own food; known as a consumer in food chain |
asexual reproduction |
a method of reproduction that requires only one parent 100% DNA from one parent |
sexual reproduction |
a method of reproduction that requires both male and female parent 50% of DNA from each 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 |

Kindom Animilia |
multicelluar, sexual and asexual, heterotropohs eukaryotic organisms; known as a consumer in the food chain |
