How are flowers organized?
A typical angiosperm flower consists of sepals, petals, stamens and carpels. The fruits and seeds develop from the carpels. The flowering plants are divided into two groups, the monocots and dicots. The Division Anthophyta is divided into two classes which include the Monocotyledones and the Dicotyledones.
What is the structure of the floral parts?

Although all flowers are different, they have several things in common that make up their basic anatomy. The four main parts of a flower are the petals, sepals, stamen, and carpel (sometimes known as a pistil). If a flower has all four of these key parts, it is considered to be a complete flower.
What does the style do in a flower?
Style – This is the name for the stalk of the pistil. When pollen reaches the stigma, it begins to grow a tube through the style called a pollen tube, which will eventually reach the ovary. The style, therefore, acts as a buffer against pollen contamination, since only compatible pollen is able to grow a pollen tube.
