Question | Answer |
---|---|
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 organlles |
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 |
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 called organism that lacks nucleus in its cell |
Domain Archaea | prokaryotic,single-celled organism that lacks nucleus in its cell and can live in extreme environments |
Domain Eukarya | organisms with cells that contain a nucleus Eukariotic |
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 1005 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 up f 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 enviorments |
kingdom Eubacteria | unicellular.asexual auto and heterotroph, prokaryotic organism that can live in moderate environments |
kingdom Protista | uni- and multi cellular sexual and asexual auto- and heterotropic eukaryotic organism that are microscopic |
kingdom fungi | uni- and multi cellular sexual and asexual heterotrophic , eukaryotic organism that are microscopic |
kingdom plantae | multicellular, sexual and a sexual autotrophs, 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 |
