When you are learning about the reproduction system of a plant, you’ll need to know and learn about the parts of its flower. Generally, the flower is the reproductive unit of some plants (angiosperms). It has some important parts such as petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs). The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tube-like structure called the style. The style leads to the ovary that contains the female egg cells called ovules. To see it more detailed, look at the following parts of a flower diagram posted below.
You can observe and look the important parts in a flower for reproduction in the parts of a flower diagram above. The stigma can take many different forms, most of them designed to help trap pollen. There are many variations on this basic structural theme. After fertilization the ovule becomes the seed and the ovary becomes the fruit. The male parts of a flower consist of one or more stamens. Each stamen is made up of paired anthers (sacs containing pollen) on a filament or stalk. The anthers are the orange/yellow structures often seen in the center of a flower. More diagrams of flower parts are below.
The picture above provides you with the detailed explanation of flower parts. Pollen from the anthers of one flower is transferred to the stigma of another usually either by wind, or by animals, especially insects. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it. The fertilized ovule becomes the seed, and the ovary becomes the fruit.
Other parts of the flower that are important are the petals and sepals. Use the unlabeled version of the diagrams as your evaluation to see whether or not you have understood the parts of a flower. Get more diagrams in the other posts of this site!
