The American Biology Teacher 1 October ; 74 8 : — The growth of pollen tubes is one of the most characteristic events in angiosperm reproduction. This article describes an activity for visualizing the journey and guidance of pollen tubes in the reproductive structures of a flowering plant. The activity uses a semi- in vivo system with rapid-cycling Brassica rapa , also known as Fast Plants. Isolated ovules were used to attract pollen tubes that were triggered to grow through explants of female flower parts.

32.1A: Plant Reproductive Development and Structure

Plant Anatomy pp Cite as. Sexual reproduction in seed plants involves the production of male and female gametes that, if successful, lead to the formation of an embryo. In order to understand the process in reasonable detail, it is necessary to know the reproductive structures—in the case of flowering plants, the reproductive structure of interest is the flower. Whether one flower supports both male and female reproductive parts or separate flowers are employed, this chapter presents these prospects and then examines the basics of floral structure and later focuses on the anatomy of male reproductive structures. Detailed steps are used to show the development of pollen and its germination prior to pollination.

Discovery of Sexuality in Plants

Land plants including spore plants and seed plants are the foundation of the Earth's ecosystem. Seed plants dominate most habitats on Earth, and angiosperms are by far the most diversified and important plant group for humans. Since the Devonian Period, land plants have undergone drastic and numerous Since the Devonian Period, land plants have undergone drastic and numerous modifications in their reproductive organs, and their success is self-evident in the great diversity of flowers all over the world. Despite lasting intensive botanical research, botanists barely know when, where, and how these modifications underwent and what organs of which groups gave rise to the flowers in angiosperms.
