1. Providing nutrients for the developing plant embryo and dispersing the plant's genetics to new locations.
2. Pollen, Stigma, Bees
3. Courtship behavior, Territorial behavior
4. Male: top, Female: bottom
5. Gametophyte, Sporophyte
6. Coevolution is when two or more species evolve together because of their interactions with one another. In this case, the zinnia flower evolved to have a shape that perfectly fits the hawk moth's proboscis to ensure effective pollination. At the same time, the hawk moth evolved to have a proboscis that fits this specific flower, ensuring it can access the nectar it needs for survival.
7. True
8. The wildflower field would likely suffer as a result of reduced pollination. With fewer bees to transfer pollen, there would be fewer plants producing seeds and new plants. This could have long-term effects on the ecosystem, as the wildflowers play an important role in providing food and habitat for many other organisms.
9. Anther, Filament, Stamen
10. By feeding on the fruit and dispersing the plant's seeds to new locations, or by serving as a pollinator for the plant's flowers.
11. The flower is the part of the plant that attracts pollinators and facilitates fertilization, leading to the production of seeds and the continuation of the species.
12. Ants use grouping for protection of the young, while elephants use grouping for cooperation.
