| Question | Answer |
|---|---|
| asexual reproduction | production of new organism requiring only one parent |
| binomial | two-part name of an organism that has been classified using the six-kingdom system |
| biology | The study of - or science of -- life |
| carnivore | an animal that extracts its energy from other animals -- meat eater |
| cellular respiration 1 | process by which producers produce energy from sugars they make during photosynthesis |
| cellular respiration 2 | process by which consumers produce energy from the food they eat |
| consumer | an organism that uses a producer or other consumer for its energy source. Ex: animals |
| controlled experiment | type of experiment where two sets are studied: a control group& an experimental group |
| control group | group in a controlled experiment that is not subject to a changed variable |
| decomposers | organisms that derive their energy from dead organisms |
| DNA-deoxyribonucleic acid | the molecule that contains the genetic material in all life forms |
| ecosystem | the relationship between more than one population & environment in which they live |
| electron microscope | microscope which bounces a beam of electrons off an object to acquire the image |
| environment | surroundings where an organism lives: external (outside: ex. rain forest) or internal (ex. human being: bacteria in blood) |
| experiment | a careful method of testing a hypothesis |
| experimental group | a group in a controlled experiment that is exposed to a variable (or change from controlled group) |
| food chain | process of the transfer of energy from the sun, to producers, to consumers, to decomposers |
| herbivore | animal that extracts its energy ONLY from plants: plant eater |
| homeostasis | maintainance of stable internal environment in order for organism to live |
| International System of Measurement or SI Units | a standard set of measurement units used by scientists all over the world |
| light microscope | a system of connected lenses which aquires an image by reflecting light off of or shining through the object |
| magnification | the amount by which an image is enlarged by a microscope |
| metabolism | process by which an organism extracts energy from its surroundings and uses it to sustain itself |
| microscope | an instrument that produces enlarged images of very small objects |
| offspring | the organism that recieves the genetic material and is formed as a result of reproduction |
| omnivore | an animal that can extract its energy from either plants or animals |
| organism | resulting structure that is formed when one or more cells are grouped together to carry on life activities. Examples range from one-celled bacterium to a trillion-celled human being or tree |
| parent | The organism(s) that supplies the genetic material during reproduction |
| photosynthesis | process by which the energy of the sun is captured in plants & used to make sugar molecules |
| population | a group of similar organisms that live in the same area |
| producer | an organism that uses photosynthesis to produce its own energy source: all plants |
| receptor | specialized molecules or organs that all life forms possess that allow them to sense and respond to changes in their environment |
| resolution | the ability to see the fine detail of an image |
| reproduction | formation of a new organism or cell from already living organisms or cells in order to propogate -or spread- the species or make new cells |
| scientific method | the systematic collection and analysis of data |
| sexual reproduction | the production of one or more offspring as a result of a male and female of the species combining their genetic material resulting in changes in genetic material from parent to offspring: requires two parent organisms |
| taxonomy | the orderly classification of plants and animals according to their observed natural relationships to one another as well as similarities in structure and function. |
| theory | a hypothesis which has undergone extensive experimentation and has been found to completely explain the question consistently |
