Across
  1. 3. A specific sequence of DNA located on a chromosome. Contains the instructions to make a specific protein, creating an organism’s traits.
  2. 5. Part of the plant that supports leaves, flowers, and fruits, transports water and dissolved substances from the roots to other parts of the plant.
  3. 9. The sticky, receptive surface at the top of a flower’s female reproductive organ where pollen grains land and begin the process of fertilization.
  4. 13. The ability of an organism to survive in its environment long enough to reproduce
  5. 14. A lack of evolutionary change over a long period during the history of a species. The species stays the same for hundreds or thousands or even millions of years
  6. 16. Organ of a plant that anchors it into the ground and takes in water and nutrients
  7. 17. The growth movement of a plant in response to light
  8. 18. Differences in the sequences of genes between individuals. This is what makes organisms of the same species look different from each other.
  9. 19. The slow, gradual genetic change in an entire population of organisms over time.
Down
  1. 1. Vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
  2. 2. A taxonomic group that includes multiple species that are closely related and share common characteristics
  3. 4. Organisms have the same structures organisms have the same structures (for example same types of bones) that have different functions (jobs) for the organism.
  4. 6. A specific characteristic of an organism. Such as eye color, height, etc.
  5. 7. Species evolve through small,sometimes hard to see, changes over long periods of time.
  6. 8. The formation of a new species can occur in a variety of ways. Final result t is a new species that can no longer successfully interbreed with the original species
  7. 10. Organism’s reaction to a stimulus (a change in an organism’s environment)
  8. 11. A molecule of DNA that is tightly coiled. Carries the genetic information of an individual. Humans have 46 (23 pairs) = ½ from father, ½ from mother.
  9. 12. A tiny opening on the surface of a plant leaf or stem, surrounded by guard cells, which control the exchange of gases like carbon dioxide and oxygen between the plant and its environment.
  10. 15. Physical or behavioral change that makes a species more likely to be successful in its environment
  11. 20. Plant structure that develops into a seed when fertilized.
