Definition |
cell |
the smallest unit of an organism that performs life functions |
nucleus |
a structure found in eukaryotic cell 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 structures function and relationship |
Domain |
the highest and largest rank of grouping organisms three group; arch, bacteria, and eukarya |
bacteria |
porkaryotic, single-celled organisms that lack a nucleus in its cell |
Archaea |
prokaryotic single-celled organisms that that lack a nucleus in its cell and can live in extreme environments |
Eukarya |
organisms with cells that contain a nucleus |
Kingdom |
a tax rank below Domain 6 groups: animalia, fungi, plantea, protista, archaed, and eulbacteria |
autotroph |
an organism that is able to make its own food; known as a producer in a food chain |
heterotroph |
an organism that can not make its own food :known as a consumer in a food chain |
asexual |
a method of reproduction that requires only one parent 100% DNA from one parent |
sexual |
a method of reproduction that requires both male and female parent 50% from one parent 50% from one parent |
cell theory |
stats that all living organisms are made up of one or more cells; cells are the basic unit of life and all cells come from other cells |
Arceabacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organisms that live in extreme environment |
Eubacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organisms that live in moderate environments |
protista |
uni-multicellular sexual or asexual auto- and heterotrophic eukaryotic organisms that are microscopic |
Fungi |
uni- and multicellular sexual or asexual, heterotrophic, eukaryotic organisms; known as a decomposer in the food chain |
Plantae |
multicellular, sexual and asexual, autotrophs, eukaryotic organisms known; as a producer in the food chain |
Animilia |
multicellular, sexual and asexual, heterotrophs, eukaryotic organisms; also known as a consumer in a food chain |
