List the main parts of the flower.

The flower is an organ that is necessary for the reproduction of most higher plants. Almost any flower consists of five main parts. This is the peduncle that connects the flower from the stem of the plant and through which the supply of nutrients occurs. It is also a sepal. The main part of any flower is the pistil and stamens. Sometimes they are on different flowers, and sometimes they are on the same flower. Another important part is the petals. They attract insect pollinators and are also capable of protecting pollen from various environmental factors.
