Include all reproductive structures.
2. Outline the steps involved in insect-pollination of a flower.
Begin with attraction of the insect to the flower.

12. Define phytochrome.
13. Distinguish between red light and far-red light.
14. Use the diagram below to help explain the interconversion of phytochromes during daylight and darkness.
15. Explain how phytochrome levels control flowering.
a. In short-day plants.
