UNIT 11 SCIENCE
SCIENCE
Term | Definition |
---|---|
cell | the smallest unit of an organism that preforms life functions |
nucleus | a structure found in Eukaryotic cells that contain DNA and is responsible for controlling the activities of a cell |
Eukaryotic | a cell containing a membrane- enclosed nucleus and organelles |
Prokaryotic | a cell lacking a membrane- enclosed organelles |
unicellular | an organism made up of one single cell |
multicellular | an organism made up of more than one cell, and often 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, Eukarya |
Bacteria | prokaryotic, single celled organism that lacks a nucleus in its cell |
Eukarya | organisms with cells that contain a nucleus |
Archaea | prokaryotic, single celled organism that lacks a nucleus in its cell and can live in extreme environments |
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 of up of 1 or more cells; cells are the basic unit or life and all cells come from other cells |
Kingdom; Archeabacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that lives in extreme environments |
Kingdom; Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that lives in moderate environments |
Kingdom; Protista | uni and multicellular sexual or asexual auto and heterotroph eukaryotic organisms that are microscopic |
Kingdom; Fungi | uni and multicellular, sexual or asexual, heterotrophic, eukaryotic organism; known as a decomposer in the food chain |
Kingdom; Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism; known as the producer in the food chain |
Kingdom; Animilia | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms; known as the consumer in the food chain |
