What is gynoecium and androecium?
Androecium and gynoecium are the two, opposite reproductive organs of the flower, the sexual reproductive structures in angiosperms. Androecium is also called stamens, which comprises of anther and filaments while gynoecium is also called the pistil or carpel, which comprises of stigma, style, and ovary.

What is the main function of gynoecium?
The female reproductive organ of angiosperms, the gynoecium, often consists of the fusion of multiple ovule-bearing carpels. It serves the important function of producing and protecting ovules as well as mediating pollination.
What is androecium write its function?
(iii) Androecium: The point of stamen, which connects the anther and the filament is called connective. Its main function is the production of microspores, i.e., pollen grains containing male gametes within the anther lobe.

In more basal families (e.g., Magnoliaceae) the carpels are spirally arranged, and in more advanced families they tend to be arranged in a single whorl.What is the example of androecium?
Stamens may be called the male parts of a flower; collectively they form the androecium. The corolla has 5 free petals and an androecium of numerous stamens, typically with filaments fused in a staminal tube (column) that surrounds the styles.Article first time published on askingthelot.com/what-is-gynoecium-in-biology/

Why is gynoecium a female reproductive organ?
The gynoecium is often referred to as female because it gives rise to female (egg-producing) gametophytes; however, strictly speaking sporophytes do not have a sex, only gametophytes do.
What is the function of gynoecium in hibiscus flower?
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.
What is the location of gynoecium?
The gynoecium, located in the fourth and innermost whorl of a flower, is the female reproductive organ of flowering plants which has specialized functions for successful pollination, seed maturation and seed dispersal.
What does the androecium produce?
