Flowers form the reproductive parts of flowering plants. Most flowers have four main parts - calyx,  corolla, stamens, and pistils. The flower parts are attached to a place on the stem called the receptacle. The calyx consists of small, usually green leaf like structures called sepals.
Angiosperms, or flowering plants, undergo a unique process called double fertilization. After pollination brings a pollen grain to a flower's female reproductive structure (carpel), a pollen tube releases two sperm cells. One of these sperm cells unites with an egg cell to produce a diploid zygote.ngiosperms are plants that produce flowers and fruits, and they are the most common types of plants on Earth. Flowers are the reproductive structures of angiosperms. They include four basic parts: 1  Carpel: Female reproductive structure that makes eggs. 2  Stamen: Male reproductive structure that makes sperm cells.
