Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants (angiosperms). Typically, they are structured in four circular levels around the end of a stalk. These include: modified leaves that support the flower; petals, often designed to attract pollinators; male parts, where pollen is presented; and female parts, where pollen is received and its movement is facilitated to the egg. When flowers are arranged in a group, they are known collectively as an inflorescence. Floral growth originates at stem tips and is controlled by specialised genes.
