Taxonomy Groups
Term | Definition |
---|---|
cell | the smallest unit of an organism that performs life function |
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 |
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 |
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 nucleus |
kingdom | a toxonomic rank below domain 6 groups: animalia, fungi, plantae, prostista, archaea, & 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; know as a consumer in the food chain |
asexual reproduction | a method of reproduction that requires only one parent/source 100% DNA from 1 parent |
sexual reproduction | a method of reproduction that requires both male and female parent 50% from 1 parent 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 archea bacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
kingdom eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
kingdom protista | uni- and multicellular sexual or asexual auto or heterotrophic eukaryotic organism that are microscopic |
kingdom fungi | uni and multicellular sexual or asexual heterotroph eukaryotic organism ; known as a decomposer in the food chain |
kingdom plantae | multicellular sexual and asexual autotroph 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 |
