The calyx part is an important part of a flower, and it consists of two parts: the sepals and the galea. The sepals are the outermost layer of the calyx and are typically green in color. They protect the flower bud and help to support the petals when the flower blooms. The galea is the innermost layer of the calyx and is usually a different color than the sepals. It helps to form the shape of the flower and can also provide additional protection for the reproductive organs of the flower.
