Summary Introduction

To explain: The way in which bisexual flowers are an advantageous evolutionary adaptation to the plants that produce them.

Introduction: Plants may have unisexual flowers or bisexual flowers. Bisexual flowers such as lily and rose have both male and female organs in the same flower. Bisexual flowers are most common in flowering plants. In gymnosperms, cones are either male or female. The presence of bisexual flowers provides an evolutionary advantage to angiosperms compared to the unisexual cones of gymnosperms.
