Reproductive Roots:
These adventitious roots are generally fleshy and develop adventitious buds. The adventitious buds can grow into new plants under favourable conditions. Such roots are called reproductive roots, e.g., Sweet Potato (vern. Shakar Kandi, Fig.

What is the function of androecium and gynoecium? Androecium is the male reproductive part of the flower. It contains anther and filament and produces pollen grains or male gametes. Gynoecium is the female reproductive part of the flower. It contains stigma, style and ovary and produces female gamete ovule, synergids, antipodals and two polar nuclei.
What is the role of androecium?
(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.
What is androecium and gynoecium? 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.
