7. a plant hormone that causes the cells of stems and shoots to grow
10. the fleshy part that surrounds and protects a seed in angiosperms
11. cells in a plant that transport water from roots to leaves
12. single cotyledon in a seed, herbaceous stem
15. male part of the flower that produces pollen and contains the anther and filament
16. plants that have bare seeds, example cones
17. the portion of a plant that contains reproductive structures that make sperm/ eggs or similar structures for a plant
19. two cotyledons in a seed, woody stem
24. female part of the flower that contains the stigma, style, and ovary
26. small chemicals made by some plant tissues that affect how other plant structures grow
27. inside some plant cell walls there are extra structures that make the plant extra strong and are sometimes used for making products for humans such as clothing
28. the repeating cycle of gametophyte and sporophyte structures in seedless plants
30. substance that plant cell walls have in them that make them strong
31. layer of living cells in a woody stem that produces new xylem and phloem cells as the plant grows

1. when a plant grows towards or away from a stimulus, could be growth toward or away from light, gravity, or a thing
2. a plant that blooms only when nights are short
3. leaf-like structure that protects the flowers outside the petals while it is developing

8. a plant that flowers regardless of the amount of light and is just dependent on temperature and moisture
9. parts of a plant leaf that contain vascular bundles with xylem and phloem
13. the protective waxy layer on the leaf of a plant
14. the portion of a plant that contains reproductive structures for asexual reproduction
15. some plants reproduce using these structures as well as spores
18. layers of xylem and phloem in a woody stem that grow larger when much water is present and smaller when less water is present
20. a plant that blooms only when nights are longer
21. the central vacuole inside a plant fills with water and pushes against the cell wall
22. layer inside a plant leaf that is on the top and contains most of the chloroplasts
23. the young plant a seed contains
25. cells in a plant that transport sugars or other nutrients from leaves to roots
29. layer inside a plant leaf that is on the bottom and contains many air spaces for oxygen and carbon dioxide
