Flowering plant reproduction

Abstract

Flowering plants, also known as angiosperms, emerged approximately 150 to 200 million years ago. Since then, they have undergone rapid and extensive expansion, now encompassing around 90% of all land plant species. The remarkable diversification of this group has been a subject of in-depth investigations, and several evolutionary innovations have been proposed to account for their success. In this primer, we will specifically focus on one such innovation: the advent of seeds containing endosperm.
