Term |
Definition |
cell |
the smallest unit of an organism that performs life functions |
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 member-enclosed organelles |
unicellular |
an organism made up of one single cell |
multicellular |
an organism made up of one or more that 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: Archean, Bacteria and Eukaryota |
Domain bactearia |
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: Animalia, Fungi, planta,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 reprodiction |
a method of reproduction that requires both male and female parent 50% from one 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 calls come from other cells |
kingdom Archeabacteria |
unicellular asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
Kingdom Eubacteria |
unicellular, sexual,auto and hererotroph prokaryotic organism that live in moderate environments |
kingdom Protista |
uni- and multi cellular sexual auto- and heterotrophic Eukaryota organism that are microscopic |
Kingdom Fungi |
uni-and multi-cellular sexual or asexual, hetero-trophic,eukaryotic organism; known as a decomposer in the food chain |
Kingdom Plantae |
multi cellular, sexual and asexual, autotrophs ,eukaryotic organism; known as a producer in the food chain |
Kingdom Animilia |
multicellular, sexual and asexual,hetrotrophs, eukaryotic organisms;known as a consumer in the food chain |
