The appearance of the first flower is an important event in the life cycle of a plant. After germination of the seed, the apical meristem initially produces only leaves. And then, abruptly, the bud produces, instead of more leaves, a new organ, a flower or an inflorescence. Although flowers, from a morphological point of view, are considered shoots with metamorphosized leaves, their structure and function are quite different from those of normal shoots and leaves. The function of the flowers is, of course, sexual reproduction and thus maintenance of the species.
