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:

  1. Identify the flower as the specialized plant part that allows for sexual reproduction.
  2. Know the structures of the flower, including the male and female reproductive features.
  3. Describe how the male and female structures operate in allowing for seed development.
  4. Differentiate plants that are monoecious or dioecious from plants that have perfect flowers.
  5. Know that flower development will occur during a specific time period.
  6. Predict the success in seed production given the synchrony and status of the development of the male and female flowers or flowering parts.
  7. Demonstrate how plant breeders use their knowledge of flowering and flower structure to make controlled crosses in plants.
  8. Choose the specific flower manipulation steps required by plant breeders who work with different plant species.
