Cell | Smallest unit that can perform life's processes |
Unicellular | Organisms that are made up of 1 cell such as bacteria |
Multicellular | Organisms made up of multiple cells such as humans or trees |
Organ | Structures that carry out specialized jobs within an organ system |
Tissue | Groups of cells that have similar abilities that allow the organ to function |
Organelle | Tiny structures that carry out functions necessary for the cell to live |
Biological Molecule | Chemical compounds that provide physical structure and that bring about movement, energy use, and other cellular functions |
Homeostasis | Constant internal condition |
Metabolism | Eat food to get energy |
Cell Division | Formation of two new cells from one existing cell |
Development | Organism becomes a mature adult |
Reproduction | Making more of themselves, essential for continuation of species |
Gene | Short segment of DNA that contains instructions for a single trait of an organism |
Domain | The three major subdivisions of all organisms |
Kingdom | Another system of grouping organisms divides all life into six major categories |
Ecology | Branch of biology that studies organisms interacting with each other and the enviroment |

Scientific Method | To learn how the natural world works |
Observation | Perceiving a natural occurrence that causes someone to pose a question |
Hypothesis | Educated guess |
Prediction | Statement that forecasts what would happen in a test situation if the hypothesis were true |
Experiment | Used to test a hypothesis and it's predictions |
Control Group | Provides a normal standard against which the biologist can compare result of the experimental group |
Experimental Group | Identical to the control group except one factor, the independent variable |
Independent Variable | What is being manipulated |
Dependent Variable | Scientist observes or measures this variable, also called the responding variable |
Theory | When a set of related hypothesis is confirmed to be true many times, and it can explain a great amount of data, scientists often reclassify as a theory |
Peer Review | Scientists who are experts in the field anonymously critique and read that research paper |
