Reproduction in plants takes place sexually and asexually as well. But the majority of the flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male and female gametes are produced by flowers. Sexual reproduction in plants takes place in flowers. The complete flower typically consists of four parts:
Petals
Sepals
Stamen (male reproductive part)
Pistil/Carpel (female reproductive part)
Stamen (male reproductive part) consists of anther and filament.
The anther is a sac-like structure that produces and stores pollen.
The filament supports the anther.
Pistil (female reproductive part) comprises of three parts- stigma, style, and ovary.
Stigma is the top most part of a flower.
The style is the long tube which connects stigma to the ovary.
The ovary contains a lot of ovules. It is the part of the plant where the seed formation takes place.
A flower may consist of either stamen or pistil or both. Based on this, a flower can be either unisexual or bisexual. A bisexual flower is composed of all the four parts mentioned above, e.g. Rose, China rose. Whereas, plants like papaya and cucumber produce only unisexual flowers.
