Abstract
What is a "flower" and what are its structures? How do the male and female parts operate to produce seed? Monoecious versus dioecious; perfect versus imperfect.
Objectives
At the completion of this lesson, the student should be able to:
- Identify the flower as the specialized plant part that allows for sexual reproduction.
- Know the structures of the flower, including the male and female reproductive features.
- Describe how the male and female structures operate in allowing for seed development.
- Differentiate plants that are monoecious or dioecious from plants that have perfect flowers.
- Know that flower development will occur during a specific time period.
- Predict the success in seed production given the synchrony and status of the development of the male and female flowers or flowering parts.
- Demonstrate how plant breeders use their knowledge of flowering and flower structure to make controlled crosses in plants.
- Choose the specific flower manipulation steps required by plant breeders who work with different plant species.
