Sexuality in Plants

A plant that possesses both male and female reproductive structures on the same plant is called a bisexual plant.

A plant in which male and female reproductive structures are present on different plants is called a unisexual plant.

A unisexual male flower that bears only stamens is called a staminate flower.

A unisexual female flower that bears only pistils is called a pistillate flower.

A plant in which both male and female flowers are present on the same individual is called a monoecious plant.

Example: Cucurbits, coconut.

A plant in which male and female flowers are present on separate individuals is called a dioecious plant.

Example: Papaya, date palm.

Plants may have male and female reproductive structures in the same plant or on different plants.
In flowering plants, male unisexual flowers are called staminate and female unisexual flowers are called pistillate.
