Plant Structure, Function, and Use


How are many flowers are easily identified based on their parts?

Many flowers can often be identified by their parts—in particular, the number of sepals, petals, and stamens. For example, a stonecrop succulent plant has thirty sepals, thirty petals, and thirty or sixty stamens; buckwheat has three to six sepals, no petals, and six or nine stamens. But it’s not really that cut and dried—for example, a jewelweed has three or five unequal sepals, one forming a spur, and five petals, two united and three separate. And with so many species of plants—including trees identified by their seeds— it’s no wonder identifying plants is truly a major study!
