This lecture explains the structure and functions of different parts of a flower, highlighting its role in plant reproduction. Students learn about the main components—pedicel, sepals, petals, stamens (anther and filament), and carpels (stigma, style, ovary)—and their specific roles in protecting the bud, producing pollen, attracting pollinators, and forming seeds. The lesson also includes practice exercises, quizzes, and diagrams to reinforce learning. Advanced notes for teachers provide deeper insights into the variation in floral part numbers across species.
