- Flowers are composed of sets of highly modified leaves arranged in whorls. The outermost whorl of a flower is called the calyx and is composed of sepals. Inside the calyx is the corolla, which is composed of petals. The sepals are often smaller and less colorful than the petals, but this general rule can be misleading.

Flowers have two primary parts: the vegetative part, which includes the petals and the sepals, and the reproductive part, encompassing the stamen (male reproductive organ) and the pistil or carpal (female reproductive organ).
The primary function of a flower is reproduction, ensuring the survival of the species. Through the process of pollination and fertilization, flowers produce seeds. Each seed contains a new plant, waiting for the right conditions to grow.
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. This process can occur through self-pollination or cross-pollination: 1. Self-pollination: This occurs when the pollen from an anther deposits onto the stigma of the same flower or another flower on the same plant. Self-pollination is common ...

Feb 28, 2021 · Flowers contain the plant’s reproductive structures. A typical flower has four main parts—or whorls—known as the calyx, corolla, androecium, and gynoecium (Figure 1). Figure 1. The four main parts of the flower are the calyx, corolla, androecium, and gynoecium.
