Seed Pollination and Germination Review

5. a mark on the seed coat showing where the ovule was attached to the ovary
7. an opening in the seed coat where the sperm entered the ovule prior to fertilization and through which water first enters the seed
8. converts carbohydrates in sugars
11. the beginning of plant growth during which the embryo inside the seed changes into a developing seedling
14. the part of the seed that develops into the first or primary root
15. Pollination of a flower on another plant
17. the ability of seeds to produce normal seedlings under less-than-optimal or adverse growing conditions
19. the portion of the embryonic shoot below the cotyledon(s) and above the radicle
21. Pollination of a flower on the same plant
22. an immature plant in an arrested state of development
23. seed dormancy mechanism whereby a seed must go through a period of cold temperatures before it will germinate

1. the ability of seeds to germinate under optimal conditions
2. the fusion of male and female gametes to form a diploid cell called a zygote (when the pollen enters the ovary)
3. a reproductive plant body that consists of a seed coat, an embryo, and stored food
4. signal the production of amylase and protease
6. the part of the seed that develops into the shoot. (includes the epicotyl & hypocotyl)
9. the first part of the new plant that emerges from the seed
10. is a protective outer covering of the seed
12. tissue that surrounds the embryo and provides nutrition in the form of starch and, to some extent, oils and proteins
13. the portion of the embryonic shoot above the cotyledon(s) that in most plants develops into the plant leaves
16. the intake of water by a seed
18. the transfer of pollen from the male to the female part of a plant
20. converts proteins into amino acids
21. a seed dormancy mechanism that involves the physical breaking down of the seed coat
