Question

Discuss the structure of gynoecium .Howard the flowers classified based on the position of the ovary

Answer 1

The gynoecium is the innermost whorl of a flower, it consists of (one or more) pistils and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells.
hypognous, perigynous, epigynous are the three types of floral arrangement based on the position of ovary.
In hypognus the ovary occupies the highest position over the thalamus.
In perigunous the ovary is situated at the centre.
In epigynous the thalamus grow around the ovary fusing with its wall.
