The flower is the sexual reproductive organ of an angiosperm.


The female part of a flower is called the carpel . It is composed of the stigma, style, and ovary within which are the ovules containing the female gametes. After pollination, the ovary becomes enlarged and contains the seeds. At this point it is called a fruit. Botanically speaking, any plant part containing seeds is a fruit. The male part of a flower is the stamen , which is composed of the anther and filament. The anther is where the male gametes, encased in pollen, are produced.


A perfect flower has both male and female reproductive organs.
Examples of plants with perfect flowers are hibiscus, apple trees, and legumes.

Not all flowers have both male and female parts.

An imperfect flower has either male or female reproductive organs, but not both. This means that plants can be male or female.

Some plants with imperfect flowers have male and female flowers on separate plants. They are said to be dioecious . They have separate sexes. The plum tree has separate sexes. There are male and female plum trees. Spinach is an example of a dioecious herbaceous plant.

Other plants with imperfect flowers are monoecious , having separate male and female flowers on the same plant, such as oak trees and corn.
