Term |
Definition |
cell |
the smallest unit of an organism that performs life funtions |
nucleus |
a structure found in Eukaryota 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 structure function and relationship |
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 an can live in extreme enviroments |
Domain Eukarya |
organisms with cells that contain a nucleus |
Kingdom |
a taxonomic rank below Domain. 6 Groups; animilia, Fungi, Plantae, Protista, Archea, 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 organism 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 environments |
Kingdom Eubacteria |
unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
Kingdom Protista |
uni- and multicellular sexual or asexual auto- and heterotrophic eukaryotic organism that are microscope |
Kingdom Fungi |
uni-and multicellular sexual or asexual auto- and heterotroph, eukaryotic 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, autotrophs, eukaryotic organism; known as a consumer in the food chain |
