Across
  1. 1. any changes in an organism's environment that cause a response
  2. 3. forms from tissue in a male reproductive structure of a seed plant
  3. 4. a plant's response to touch
  4. 8. a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP
  5. 10. the ovary, and sometimes other parts of the flower, will develop into this, which contains one or more seeds
  6. 12. when the life cycle of an organism alternates between diploid and haploid generations
  7. 14. the vascular tissues that transport materials through a plant
  8. 17. substances that act as chemical messengers within plants
  9. 21. hormones produced in rapidly growing areas of a plant that increase the rate of cell division and elongation
  10. 23. the growth of a plant toward or away from light
  11. 24. plant hormone that causes increased growth
  12. 26. a thing at the base of the style which contains one or more ovules
  13. 27. the process during which a nucleus and its contents divide
  14. 28. a response that results in plant growth toward or away from a stimulus
Down
  1. 2. plants that flower when exposed to less than 10-12 hours of darkness per day
  2. 5. a flowerless seed plant
  3. 6. the pigment that absorbs light for photosynthesis
  4. 7. flowering plants
  5. 9. the daughter cells produced from haploid structures
  6. 11. plant hormone that helps stimulate the ripening of fruit
  7. 13. the male reproductive organ of a flower
  8. 15. a series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen
  9. 16. hormones produced in root tips that increase the rate of cell division, and occasionally slow the aging process of flowers and fruit
  10. 17. the female reproductive organ of a flower
  11. 18. the female reproductive structure of a seed plant where the haploid egg develops
  12. 19. a plant's response to the number of hours of darkness in it's environment
  13. 20. an immature diploid plant that develops from the zygote
  14. 22. when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grains
  15. 25. a plant's response to gravity
  16. 29. made up of an embryo, its food supply, and a protective covering
