Final answer:
The four typical whorls in a flower are the calyx (sepals), corolla (petals), androecium (stamens), and gynoecium (carpels). While the calyx and corolla form the flower's protective and attractive structures, the androecium and gynoecium contain the male and female reproductive organs, respectively.
Step-by-step explanation:
The four whorls typically found in a flower are calyx, corolla, androecium, and gynoecium. The outermost whorl is the calyx, composed of sepals, which protect the developing bud. The second whorl, the corolla, consists of petals and often serves to attract pollinators with its vivid colors. The androecium represents the third whorl and contains the male reproductive structures called stamens, each of which includes a filament and an anther where pollen is produced. The innermost whorl is the gynoecium, which comprises the female reproductive organs, and includes the carpels made up of the ovary, style, and stigma. Inside the ovary, ovules develop, which eventually become seeds after the process of fertilization.
It's important to note that the terms provided in the initial query (xylem, phloem, cortex, pith) are related to plant anatomy but do not relate to the flower's reproductive whorls. These elements are part of a plant's vascular system, which is involved in the transport of water and nutrients.
