Reproduction of Corn. Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination. … Non flowering plants reproduce either from spores, suckers or runners. Asexual reproduction is through stems, roots and leaves. Reproduction in flowering plants begins with pollination, the transfer of pollen from anther to stigma on the same flower or to the stigma of another flower on the same plant (self-pollination) or from the anther on one plant to the stigma of another plant (cross-pollination).

Although these structures are the product of meiotic divisions, the spores are recognized as specialized “asexual” structures in these organisms, since when they germinate they can produce new individuals directly, without the fusion between several of them. • Producing seeds requires combining a pollen grain and ovum. Others believe that the development of a flower is caused by the union of a male and female stamen and vesicle, with the union of these two cells forming the flower. Contributors unite from different perspectives and disciplines, ranging from agronomy and hydrology to economics.
