Question | Answer |
---|---|
cell | the smallest unit of an organism life functions |
nucleus | a structure found in enkaryatic cells that contain DNA and is responsible for controlling the activities of the cell |
eukaryotic | a cell containing a membrane-enclosed 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 structure, function and relationship |
domain | the highest and largest rank of grouping |
bacteria | prokaryotic single celled organisms that lacks a nucleus in a its cell |
archaea | prokaryotic single celled organism that lacks a nucleus in its cell and can live in extreme environments |
eukarya | organisms with cells that contain a nucleus |
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 the 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 1 parent. 100%DNA from 1 parent |
sexual reproduction | a method of reproduction that requires both male and female parents. 50%from 1 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 cell come from other cells |
archeabacteria | unicellular, asexual, auto and hetrotroph, prokaryotic organism that live in extreme environments |
eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organsim that live in moderate environments |
protista | uni- and multicellular, sexual or a sexual auto- and heterotrophic, eukaryotic organism that are microscopic |
fungi | uni-and multicellular sexual or asexual, heterotrophic, eukaryotic ;known as a decomposer in the food chain |
plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism ;known as a producer on the food chain |
animilia | multicellular, sexual, and asexual, heterotrophs, eukaryotic organisms; known as a consumer in the food chain |
