Flowers are the beautiful part of plants that gives us the visual attraction. We all love flowers and their good smell. Many people visit the parks and forests to see plants and the flowers. You may be familiar with the famous Rose flower, which has red color and a good smell. So, how plants produce flower and why? Let’s find out!
What is Flower?
A flower is the reproductive part of the plant which contains the sex organs of a plant. They produce seeds for the new plants by pollinating. The main features of a flower are sepal, petal, stamen, filament, anther, pistil, stigma, and carpel.
Life Cycle of the Flowering Plants
A flowering plant starts its life as a seed, which is germinated to grow its first roots and leaves. The plant then continues to grow and takes necessary things for their growth, until it reaches its full maturity.
The mature plants produce flowers, which when pollinated produce seeds. These newly produced seeds again start their life and follow the same cycle.
When flowers are produced, they need to be pollinated for making seeds. Plants pollinate when the pollen from the male part of a plant called anther reaches its female part called ovary. As a result, the fertilization takes place and new seeds are produced.
Pollination of Plants Methods
- Plants produce the flowers that attract many insects and birds. These insects and birds get the pollen on their body. When they go from flower to flower the pollen is dropped.
- Air plays an important part for pollinating plants that are far away from each other. The air carries pollen from plants and takes it away to other plants.
- Humans also take the pollen from one plant and move it to another plant for increased fertility.
The seed must be germinated in order to grow as a plant. For germination, it needs many necessary things including the rich soil and water (see How Plants Grow). There many ways in which seeds disperse across the land. Some are given below:
- Rivers and Streams
- Many flowers are used to make scent due to their good and attractive smell.
- Rafflesia arnoldii is the largest flower. It grows as large as 3 feet and can weigh 15 pounds.
- Wolffia is the smallest flowering plant, which about the size of rice grain.
