Across
  1. 3. plant hormone that helps stimulate the ripening of fruit
  2. 4. male reproductive organ of a flower
  3. 5. developed from the ovary and sometimes other parts of the flower, and contains one or more seeds
  4. 6. at the base of the style and contains one or more ovule
  5. 8. the growth of a plant towards or away from light
  6. 10. daughter cells produced by haploid structures
  7. 12. plants that flower when they reach maturity and the environmental conditions are right
  8. 14. useable power
  9. 16. plant hormone that generally cause increased plant growth
  10. 17. substances that act as chemical messengers with plants
  11. 18. haploid and diploid stages in the life cycle of a plant
  12. 19. a plant’s response to the number of hours of darkness in its environment
  13. 23. any changes in an organism’s environment that cause a response
  14. 24. plant hormone that increases the rate of cell division and cell elongation
  15. 26. the process during which a nucleus and its contents divide
  16. 27. plants that flower when exposed to less than 10/12 hours of darkness
  17. 28. when the life cycle of an organism alternates between diploid and haploid generations
Down
  1. 1. plants that require 12 or more hours of darkness for flowering to begin
  2. 2. a series of chemical reactions that convert the energy in food molecules into a useable form of energy called ATP
  3. 7. female reproductive organ of a flower
  4. 9. female reproductive structure of a seed plant where the haploid egg develops
  5. 11. when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grain
  6. 13. a response that results in plant growth towards or away from a stimulus
  7. 15. response of a plant to gravity
  8. 19. a series of chemical reactions that convert light energy, water, and carbon dioxide into the food/energy molecule glucose and give off oxygen
  9. 20. response of a plant to touch
  10. 21. forms from tissue in a male reproductive structure of a seed plant
  11. 22. plant hormone that increases the rate of cell division and in some plants, can slow the aging process of flowers and fruits
  12. 23. made up of an embryo, food supply, and a protective covering
  13. 25. immature diploid plant that develops from the zygote
