The flower of a plant is typically the reproductive part that helps to produce seeds for future generations of the plant. Flowers are often pollinated either by insects or wind. Plants with "perfect" flowers contain both female and male reproductive parts. However, there are also "imperfect" flowers in which separate flowers either contain male or female flowers. Some plants may also contain all female or all male flowers. Regardless, most flowers have typical parts that make up its structure.
The stamen is the male part of a flower, and is where pollen is produced. You will typically find the same number of stamens in a flower as there are petals. The stalk of the stamen is called the filament. At the end of the filament, is the anther. The anther is the part of the stamen that produces and contains the pollen which is needed to pollinate the female stigma of a flower.
The pistil is the female part of a flower. The stalk of the pistil is the style. At the end of the style is the stigma. The stigma is the sticky, bulb-like part of the pistil that receives the pollen from the male anther. It is essential that pollen is fertilized on the stigma in order to produce an ovule or seed. The ovule is found within the ovary of a flower. Typically, the ovary is found at the bottom of a flower, and is the part which turns into fruit.
The structural parts that make up the base of a flower include the peduncle. The peduncle is the stalk of the flower, which helps to support it. The receptacle is the part attached to the stalk at the base of the flower. It is also the part that bares the male and female parts of the flower. The sepals are the leaf-like structures that initially protect the flower when it is a bud, and which are at the base of the flower once it opens.
The most colorful part of a flower is the petals. The petals help to attract insects that aid in transporting pollen between the male anther and female stigma. Petals attract insects through their bright colors. They also provide nectar, which is a food source for butterflies, bees and other insects.
