In a garden, we notice various kinds of flowers. Flowers are considered to be the reproductive part of the plant. When we observe it closely, we find that it possesses both the male and female reproductive organs. Let us study the structure of flower in detail. At the axis of the flowering branch, we find small leaf like outgrowths called the bracts. The stalk of the flower is called the pentacle. Which has a swollen structure known as the thalamus. Calyx is the outermost whirl of the flower. It is composed of sepals which are usually green in color. It is the outermost non-essential world of the flower. And one of its main functions is to protect the flower in bud stage. Being green in color, it also helps in photosynthesis. The next inner world is corolla. It is composed of petals, which are large and showy. They are brightly colored, and attract insects for pollination. Next inner world is the andreassen. Which is composed of a number of stamens. Each stamen consists of a filament, anther and a connective. A close observation of the anther shows the presence of two lobes called the anther lobes. Each of these contains numerous pollen grains. When the stamen is mature, these pollen grains are released. Magnified view of a pollen grain shows the hard thorny outer covering called the axon. Below this is a soft layer called in time. We also find a nucleus and a generative cell embedded in the cytoplasm. If we closely observe the gyne sh, which is the female reproductive part of the flower. It has a terminal knob like portion known as the stigma. The stigma continues as a thin stock like structure called the style. Which ends into a swollen pear shaped body known as ovary. A section of the ovary shows chambers known as locules. Inside these locules, we find the ovules. The ovules are attached to the ovary by the placenta. Which is a thin layer of tissue. In a recap, we see that a typical flower has four whorls. Calyx is the outermost world. It is made of units called sepals. Next world is the corolla, which is composed of bright petals. Inter to petals is the male reproductive world called Andrea. Its units are called stamens. They produce pollen which helps in pollination. The innermost whorl is the gyne sh, which is the female reproductive world. These four whorls together form a complete flower.
