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 a nucleus or any other membrane-enclosed organelles |
unicellular |
an organism made up of one single cell |
multicellular |
a 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 eukarya |
bacteria |
prokaryotic single celled organism that lacks a nucleus in its cell |
archaea |
prokaryotic single celled organism that lacks a nucleus in its cell and can live in extreme environments |
eukarya |
organisms with cells that contain a nucleus |
kingdom |
a taxonomic rank below domain 6 groups anamilia fungi plantae protista 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 the consumer in the food chain |
asexual |
a method of reproduction that requires only 1 parent 100% DNA from 1 parent |
sexual |
a method of reproduction that requires both male and female parent 50% 1 parent 50% 1 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 |
archeabacteria |
unicellelar, asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
eubacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
protista |
uni and multicellular sexual or asexual, heterotrophic eukaryotic organism that are microscopic |
fungi |
uni and multicellular sexual or asexua, heterotrophic, eukaryotic organism; known as decomposer in food chain |
plantae |
multicellular, sexual and asexual, autotrophs, eukaryotic organism; known as producer in food chain |
animilia |
multicellular, sexual and asexual, heterotrophs, eukaryotic organism; known as the consumer in the food chain |
