- 6. The growth movement of a plant in response to light.
- 7. A molecule that can be bonded to another identical molecule.
- 9. A lack of evolutionary change over a long period during the history of a species. The species stays the same for hundreds of thousands or even millions of years.
- 10. Passing of traits from parents to child. Genes on chromosomes control the traits that show up in an organism.

- 2. Organisms reaction to a stimulus or a change in an organisms environment.
- 3. Vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
- 4. Regulation of an organism's internal environment to maintain conditions needed for life.
- 5. The end result of a biological or chemical process, what was made or created.
