Across
  1. 2. cell - the photosynthetic cells found in leaves of plants.
  2. 3. effect - the reduced genetic diversity in a new population caused by a small number of individuals being separated from a larger population. This will cause the new population to end up with a significant genetic difference from the original population.
  3. 7. flow - The movement of genes from one population to another population of the same species. For example, White tailed Deer from one herd migrate into another herd's territory, and breed with the new herd. This helps improve and increase genetic diversity
  4. 9. system - the above ground part of a plant, including stems, leaves, flowers, and fruits, which are responsible for photosynthesis, nutrient transport, and reproduction.
  5. 11. - organ of a plant that anchors it into the ground and takes in water and nutrients.
  6. 15. - organism’s reaction to a stimulus (a change in an organism’s environment)
  7. 18. drift - A particular gene is lost due to chance.This will cause the population to change, with some traits disappear completely.
  8. 19. - the formation of a new species can occur in a variety of ways. Final result is a new species that can no longer successfully interbreed with the original species
  9. 20. of evolution - Data gathered that supports evolution. Homologous structures, fossil record, embryology, molecular biology
  10. 21. - 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
  11. 25. - vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
  12. 27. structure - organisms have the same structures (for example same types of bones) that have different functions (jobs) for the organism.
  13. 30. significant - Something that has given a species an advantage in its environment. For example: Humans standing on 2 legs is evolutionarily significant.
  14. 33. - species evolve through small, sometimes hard to see, changes over long periods of time. Suggests that evolutionary processes are continuous.
  15. 34. - physical or behavioral change that makes a species more likely to be successful in its environment.
  16. 35. appearance - new species that appear suddenly in the fossil record
  17. 36. system - the body system that works to control and coordinate all bodily functions and includes nerve cells (neurons), the brain and the spinal cord.
  18. 37. system - the body system involved in breathing and gas exchange and includes the nasal passages, the pharynx, the larynx, the epiglottis, the trachea, bronchi, the lungs, and the diaphragm.
Down
  1. 1. system - body system that works to protect the body from infection and disease and includes the skin, mucus, and white blood cells.
  2. 4. system - body system that removes waste and excess water from the body and includes the lungs, skin, kidneys, and urinary bladder.
  3. 5. - the slow, gradual genetic change in an entire population of organisms over time...a looooooooong time!
  4. 6. - the growth movement of a plant in response to light
  5. 8. system - body system that functions as a communication system and includes the pituitary gland, the thyroid gland, the parathyroid gland, the thymus gland, the pineal gland, the pancreas, the adrenal glands, the ovaries, and the testes.
  6. 10. - The ability of an organism to survive in its environment long enough to reproduce
  7. 12. - Differences in the sequences of genes between individuals. This is what makes organisms of the same species look different from each other.
  8. 13. - plant structure that develops into a seed when fertilized.
  9. 14. - a taxonomic group that includes multiple species that are closely related and share common characteristics
  10. 16. - part of the plant that supports leaves, flowers, and fruits, transports water and dissolved substances from the roots to other parts of the plant.
  11. 17. system - the body system involved in producing offspring
  12. 18. cell - one of a pair of cells that function in the opening and closing of a plant’s stomata by changes in their shape.
  13. 22. - 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.
  14. 23. system - a network of tissues and vessels that carry blood and lymph through the body and includes the heart, arteries, veins and capillaries.
  15. 24. - the sticky, receptive surface at the top of a flower’s female reproductive organ, where pollen grains land and begin the process of fertilization.
  16. 26. - A group of organisms that can interbreed and produce viable offspring (Viable means able to have offspring of their own.)
  17. 28. ancestor - An organism far back in geological history that 2 or more current organisms can be traced back to. For example: all birds can be traced back to small theropods (like a small T-Rex). So a common Ancestor for birds would be theropods.
  18. 29. structure - features in different species that perform similar functions but do not have the same structure (how it's made). These species do not have a common ancestor.
  19. 31. selection - Food and resources are limited so organisms have to COMPETE to get them. Not all offspring will survive only the MOST FIT (not always the strongest!)
  20. 32. system - the body’s largest organ that consists of skin, hair, and nails.
  21. 33. gravitropism - the growth of plants in respect to gravity; roots are positive because they grow down and stems are negative because they grow up against gravity.
  22. 38. mutations - Creates small changes in individuals that may have an effect on the organism's fitness (ability to pass their genes on to another generation) If the mutation causes the individual to be more successful in the environment, it will pass that trait to its offspring, and it will eventually spread through the population over generations.
