A flower is a modified shoot. A flower bud is formed when shoot apical meristem in angiospermous plants gets transformed into floral meristem and leaves transform into floral appendages.
In angiosperms, flowers are the reproductive units and they are meant for sexual reproduction. A typical flower possesses four types of floral organs or whorls — sepals (calyx) , petals (corolla), stamens (androecium), and carpels (gynoecium). These whorls are arranged on the swollen end of the stalk or pedicel, called the thalamus or receptacle.
Flowers are the place where pollination takes place. Due to the vibrant color and fragrance of flowers, insects get attracted to them that helps in the process of pollination that in turn leads to seed production. These seeds turn into fruits and are also a very important part of plant survival as they create new plants.
