How Do Flowers Reproduce?

Flowers are colorful, flashy, fragrant and are the plant's reproductive structures. Their beauty is why we're attracted to them.  Not only us, but also insects who receive nourishment in exchange for pollination and help ensure their survival. Reproduction in flowering plants begins with pollination, which is the transfer of pollen from one flower to another. This can sometimes happen and be successful on the same plant (self pollination), or from one plant to another


Once the pollen grain lodges itself on the stigma (that sticky end on the flower), a pollen tube will grow from the pollen grain down to the ovule. Much like reproduction in humans it is essentially a sperm and a egg coming together. Two sperm nuclei then pass through the pollen tube, and then one of them unites with the egg nucleus and produces a zygote. The other sperm nucleus unites with two polar nuclei to produce an endosperm nucleus. The fertilized ovule develops into a seed.
