Therefore, corolla or petals merely refers to the second whorl of a flower, which is interior to the calyx.
Like calyx, corolla can also be gamopetalous fused and polypetalous free. Like calyx, corolla can be free polypetalous or fused gamopetalous. In polypetalous corolla, all the petals remain free in origin. In the gamopetalous corolla, the united and free portion is called corolla tube and corolla lobes, respectively. Throat refers to the junction of the tube and lobe. The shape and size of the corolla in plants differ among different species, and it is classified into regular or irregular form.
The third whorl contains the male reproductive structures and is known as the androecium. The androecium has stamens with anthers that contain the microsporangia. The innermost group of structures in the flower is the gynoecium , or the female reproductive component s. The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary. A flower may have one or multiple carpels.
Figure 1. The four main parts of the flower are the calyx, corolla, androecium, and gynoecium. The androecium is the sum of all the male reproductive organs, and the gynoecium is the sum of the female reproductive organs. If all four whorls the calyx, corolla, androecium, and gynoecium are present, the flower is described as complete. If any of the four parts is missing, the flower is known as incomplete. Flowers that contain both an androecium and a gynoecium are called perfect, androgynous or hermaphrodites.
There are two types of incomplete flowers: staminate flowers contain only an androecium, and carpellate flowers have only a gynoecium Figure 2. Figure 2. The corn plant has both staminate male and carpellate female flowers. Staminate flowers, which are clustered in the tassel at the tip of the stem, produce pollen grains.
