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 and organelles |
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 cell |
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 |
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 enviroments |
Domain Eukarya |
organisms with cells that contain a nucleus |
Kingdom |
a taxonomic rank below Domain 6 groups: Animalia, 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 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 unit of life and all cells come from other cells |
Kingdom Archeabacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme enviroments |
Kingdom Eubacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate enviroments |
Kingdom Protista |
uni- and multi-cellular sexual or asexual auto- and heterotrophic eykaryotic organism that are microscopic |
Kingdom Fungi |
uni- and multicellular sexual or asexual, heterotrophic, eykaryotic organism; known as a decomposer in the food chain |
Kingdom Plantae |
multicellular, sexual and asexual, autotrophs, eukaryotic organism; known as a producer in the food chain |
Kingdom Animilia |
multicellular, sexual and asexual, heterotrophs, eukaryotic organism; known as a consumer in the food chain |
