Bio Ch. 14 plant Class/Structure Part 2
Across
- 2. the female reproductive structure of a flower
- 3. a layer of meristematic cells located between the xylem and phloem in the woody stems of plants that produces new vascular tissues
- 6. any flowering plant whose embryo has two cotyledons
- 7. the leaf of a fern plant
- 8. a structure on the underside of a fern front that houses and protects the fern's
- 10. the male reproductive structure of a flower; produces pollen
- 13. the thickened top portion of a pedicel that supports the actual parts of a flower
- 16. in plants, the fertilization of both the egg cell and the polar bodies, which later form the endosperm
- 18. a structure within a plant seed that nourishes the developing embryo and may, upon germination of the seed, become the seedling's first leaves
- 19. an area of porous tissue in the surface of a woody plant stem that allows for gas exchange with the environment
- 20. the structure in a plant ovary that contains the egg cell and will mature into a seed
- 21. leaflike structure that protects a flower bud while forming and supports the flower after blooming
- 22. the haploid stage in the alternation of generations life cycle of plants, during which gametes are produced
- 23. a root system lacking a taproot and consisting of many small roots that comes straight from a stem
Down
- 1. a root system consisting of a large, main root (the taproot) from which smaller roots branch
- 4. the stalk that connects a flower to the rest of the plant
- 5. a ripened plant ovary with or without seeds
- 9. a flower structure located just inside the sepals that is often large, conspicuous, and scented
- 11. a visible ring caused by yearly growth in the vascular cambium; seen in a cross-section of a woody stem
- 12. the diploid stage in the alternation of generations life cycle of plants, during which spores are produced
- 14. the spongy ground tissue located in the center of an herbaceous plant stem
- 15. any flowering plant whose embryo has one cotyledon
- 17. the stored food inside a plant seed
- 22. the beginning of growth by a seed, spore, bud, or other structure after a period of dormancy
