Across
- 3. any changes in an organisms environment that cause a response
- 7. the ovary, and sometimes other parts of the flower, will develop into a fruit that contains one or more seeds
- 10. a slender threadlike object or fiber, especially one found in animal or plant structures
- 13. the base of the style, which contains one or more ovules
- 14. hormones that generally increase plant growth
- 17. when a plant's sperm and a plant's egg combine to create offspring
- 18. hormone that increases the rate of cell division, and in some cases can slow the aging process of flowers and fruits
- 19. plants that flower when exposed to less than 10 to 12 hours of darknes
- 21. male reproductive organ of a flower
- 22. female reproductive organ of a flower
- 24. a response that results in plant growth toward or away from a stimulus
- 26. daughter cells produced from haploid structures
- 27. the part of a stamen that contains the pollen
- 28. a series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen
- 29. occurs when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grains
Down
- 1. plants that require 12 or more hours of darkness to flower
- 2. when a portion of a plant separates into a new plant, creating a genetically identical offspring
- 4. the growth of a plant towards light
- 5. a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP
- 6. hormones that increase the rate of cell division and cell elongation
- 8. occurs when the life cycle of an organism alternates between diploid and haploid generations
- 9. immature diploid plant that develops from the zygote
- 11. female reproductive structure of a seed plant where the haploid egg develops
- 12. plants that flower when they reach maturity and the environmental conditions are right
- 15. a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
- 16. forms from tissue in a male reproductive structure of a seed plant
- 20. a plant's response to the number of hours of darkness in its environment
- 23. hormone that helps stimulate the ripening of fruit
- 25. an embryo, its food supply, and a protective covering
- 28. hormones substances that act as chemical messengers within plants
