Final answer:
The gladiola has sepals, petals, stamens, and carpels, which are the usual flower parts of a monocot. Sepals protect the unopened bud, petals are brightly colored, stamens hold pollen, and carpels are the female reproductive structures.
Step-by-step explanation:
The gladiola has the usual monocot flower parts. The outermost whorl of the flower is the calyx, which consists of green, leafy structures known as sepals that protect the unopened bud. The second whorl is comprised of brightly colored petals that together form the corolla. The male reproductive structures, called stamens, are located in the third whorl and have anthers that hold the pollen. The innermost group of structures in the flower is the female reproductive component(s) known as the carpel(s), which consists of a stigma, style, and ovary.
