What term describes a flower that has both stamens and pistils?

A flower that possesses both stamens (the male reproductive part) and pistils (the female reproductive part) is described as perfect. This term signifies that the flower has the ability to produce both male and female gametes, making it capable of self-pollination or cross-pollination. Such flowers are significant in plant reproduction since they can contribute to genetic diversity through sexual reproduction.

In contrast, the other terms refer to different characteristics of plant reproductive structures. An imperfect flower, for instance, contains either stamens or pistils but not both, which means it cannot self-pollinate. Monoecious refers to a plant species having both male and female flowers on the same individual, while dioecious describes species where male and female flowers are found on separate individuals. The distinction of a flower being perfect emphasizes its complete reproductive capability, which is essential for understanding plant biology and ecology.
