SCIENCE
Term | 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 or any other menbrane - 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 os scince 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 | prokaryotoc, singlecelled organism that lacks a nucleus in its cell |
Domain Archaea | prokaryotic, singlecelled 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, Archaea, and Eubacteria |
autotroph | an organism that is able to make its own food; know 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 | atates 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 multicellular sexual or asexual auto- and heterotrophic eukaryotic organism that are microscopic |
kingdom Fungi | uni- and multicellular sexual or asexual, heterotrophic, eukaryotic organism; know as a decomposer in the food chain |
kingdom Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism; know as a produces in the food chain |
kingdom Animilia | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms;know as a consumer in the food chain. |
heterotroph | an aorganism that CANNOT make its own food; known as a consumer in the food chain |
