Petals 

Petals attract insects with their colors. These help in pollination. 

Sepals 

Sepals are small, green, leaflike structures on the base of the flower that protect the flower bud. The sepals collectively are called the calyx

Male Flower Parts 

The stamen is the organ that produces pollen. The filament is a thin, long stem that supports the anther with its pollen. The anther produces the grain pollen. 

Female Flower Parts 

The pistil is located in the center of the flower. The stigma receives the pollen. It can be feathery, sticky, hairy, or shaggy. The style acts like a passageway for pollen to reach the ovary. The ovary is where seeds develop. The ovule is located inside the ovary and contains an immature seed.
