What is a complete flower?

A complete flower is characterized by the presence of both male and female reproductive structures. Specifically, it contains stamens, which are the male parts that produce pollen, and pistils, which are the female parts that house the ovary and receive pollen. This combination allows for the possibility of self-pollination and ensures that the flower can engage in reproduction without the need for another flower to provide pollen.

Flowers that are only male or only female do not possess both types of reproductive organs and therefore cannot be classified as complete. A flower without any reproductive parts would not be able to fulfill the reproductive function at all, making it incomplete in terms of flower structure. Thus, the definition of a complete flower aligns perfectly with the presence of both male and female parts, enabling reproductive functions within that individual flower.
