Definition |
cell |
the smallest unit of an organism that performs life functions |
nucleus |
a structure fond 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 |
Prokaryoyic |
a cell lacking a nucleus of 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 relationships |
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 taxonomic rank below Domain 6 Groups; Animal, Fungi, Plantae, Protista, Archaed, and Eubacteria
|
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 parent 50% from 1 parent |
cell theory |
states that all living organisms are made up of 1 or more cells; cells are the basic come from other cells |
kingdom Archeabacteria |
unicellilar, 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, heterotrophic, eukaryotic organism that are microscopic |
kingdom Fungi |
uni-and multicellular sexual or asexual heterotrophic, eukaryotic organism; known as a decomposer in the food chain |
kingdom Plantea |
multicellular sexual and asexual, autotrophs, eukaryotic organism; known as a produser in the food chain |
kingdom Animilia |
multicelular, sexual and asexual, heterotrophs, eukaryotic organism; known as a comsumer in the food chain |
