Question

What happens to the stamens after fertilization?

Answer 1

Hint: The flower is one of the most important parts of the plants. Flowers contain the plant’s reproductive structures. The calyx, corolla, androecium, and gynoecium are the important parts of the flower.

Complete answer:
A flower is a reproductive structure that is required for production of seeds or fruits and is mainly found in the flowering plant. Petals refer to the bright-coloured part that helps to differentiate one flower from others and sepal is the green-coloured part found beneath the petals. The sepals are collectively called the calyx which helps to protect the rising bud.
The second whorl is composed of petals which are collectively called the corolla. The third whorl is known as the androecium. It contains stamens with anthers which bear the microsporangia. The innermost group of structures in the flower is the gynoecium which is the female reproductive part of the flower and it possesses a stigma, style, and ovary. It is also known as carpels.
The male reproductive part of the flower are the stamens. It is composed of a filament which is a thread-like structure with a circular structure anther on the top. Pollen is produced by the anther. The fusion of stamens and could be generally in two forms which are filament fusion and syngenesious.
During fertilization, the male gametes i.n. pollen gets fused with the female gametes i.e. ovum and generates a diploid zygote. Later, the zygote develops into a seed.
Just after the fertilization, some parts of the flower may fall off and remain intact while some are transformed. The ovary of the flower gets enlarged and forms the fruit while the ovarian wall forms the fruit wall. The ovules present in the ovary develop to give rise to the seeds. The calyx can either remain intact or fall off. The stamens, style, petals, and stigma of the flower fall off as they are no longer required.


Note: A flower consists of mainly four parts, they are petals, sepals, male reproductive parts, and female reproductive parts. The male reproductive part is the stamen which consists of anthers and filaments and the female reproductive part is the ovary and ovules. After fertilization, the ovary transformed into fruit, and the ovule transformed into a seed. The stamens, style, petals, and stigma of the flower fall off.
