Flower- notes

A flower is the part of a plant that blossoms. Flowers produce the seeds that can become new plants. Flowers vary widely in their shape, size, colour and scent. Many types are small and barely noticed. The blossoms that most people think of as flowers are those that are colourful and showy. A flower usually has four main parts. These are the calyx, the corolla, the stamen and the pistils. All of these parts are usually bunched together at the trip, or receptacle, of the flower step. 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 flowers' petals form a corolla. Within the corolla are the stamens and the pistils. The stamens are the male parts of a flower. 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 neither stamen or pistils.
