Answer :
Final answer:
A flower is primarily made up of four parts: the calyx (sepals), corolla (petals), androecium (male reproductive organs), and gynoecium (female reproductive organs). If all these parts are present, it is a complete flower, but the lack of any makes it an incomplete flower. Details about each part provide insight into the reproductive structures present in plants.
Explanation:
A typical flower has four main parts or whorls, labelled as the calyx, corolla, androecium, and gynoecium. The term calyx refers to the leafy structures known as sepals, while petals are collectively called the corolla. Together, these two form the perianth. The androecium is the term used for all male reproductive organs; it contains stamens which produce pollen. On the other hand, the gynoecium refers to the sum of the female reproductive organs, which includes the carpel consisting of the stigma, style, and ovary. If all four parts are present, it is a 'complete' flower, those missing any part are classified as 'incomplete'. Some flowers are only having an androecium or a gynoecium, defining them as staminate or carpellate flowers.
