Definition |
cell |
the smallest unit of an organism that performs life function |
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 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 |
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 and can live in extreme environments |
domain eukarya |
organisms with cells that contain a nucleus |
kingdom |
a toxonomic rank below domain 6 groups: animalia, fungi, plantae, prostista, archaea, & 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; know as a consumer in the food chain |
asexual reproduction |
a method of reproduction that requires only one parent/source 100% DNA from 1 parent |
sexual reproduction |
a method of reproduction that requires both male and female parent 50% from 1 parent 50% from the other 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 archea bacteria |
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 or heterotrophic eukaryotic organism that are microscopic |
kingdom fungi |
uni and multicellular sexual or asexual heterotroph eukaryotic organism ; known as a decomposer in the food chain |
kingdom plantae |
multicellular sexual and asexual autotroph eukaryotic organism known as a producer in the food chain |
kingdom animilia |
multicellular sexual and asexual heterotrophs eukaryotic organisms known as a consumer in the food chain |
