 A flower is the part of a plant that blossoms. Flowers produce the seeds that can become new plants. Most plants, including many trees, grow some kind of flower.

Flowers vary widely in their shape, size, color, and scent. Many types are small and barely noticeable. The blossoms that most people think of as flowers are those that are colorful and showy.

A flower usually has four main parts. These are the calyx, the corolla, the stamens, and the pistils. All of these parts are usually bunched together at the tip, or receptacle, of the flower stem.

The calyx is the outermost part of a flower. It is made up of sepals. The sepals are usually green and look like small leaves. The sepals enclose and protect the flower bud while it is developing into a flower.

The flower’s petals form the corolla. Within the corolla are the stamens and the pistils. The stamens are the male parts of a flower. They produce tiny grains called pollen. Pollen grains contain sperm cells. The pistils are the female parts of a flower. The pistils contain egg cells that can develop into seeds. Some flowers have both stamens and pistils. Others have either stamens or pistils.

Pollination is the process by which flowers form seeds. This is how plants reproduce.

There are two main kinds of pollination: self-pollination and cross-pollination. Self-pollination is the transfer of pollen from a stamen to a pistil on the same plant. This can happen within one flower or between different flowers on the plant. Cross-pollination is the transfer of pollen from a flower on one plant to a flower on another plant.

Flowers depend on carriers for cross-pollination. Carriers are things that carry pollen from one plant to another. They include the wind, insects, birds, and other animals.

After a grain of pollen lands on a flower’s pistil, fertilization occurs. That is, a sperm cell from the pollen enters the egg cell in the pistil. The fertilized egg then grows into a seed.

Flowers are symbols of beauty in most cultures of the world. Many people give flowers as gifts. People also use flowers as decorations during holidays and at weddings and other ceremonies. Flowers with a lovely scent may be made into perfume.
