Symptoms of food intolerance are often confused with food allergy and coeliac disease, but food intolerance really is very different. Food intolerance is not life threatening, nor is it necessarily lifelong, but it does have a big impact and it has been estimated that (at least) 45% of the population suffers.
If you look inside a typical flower, you will see many small parts. The male reproductive part of a flower is called the stamen. It is composed of a long tube, called a filament, and has a pollen-producing structure on the end. This oval-shaped structure is called the anther.It is crucial in the reproduction of flowering plants, as it produces the male gametophyte, known as pollen.f you look inside a typical flower, you will see many small parts.

Pollen in Angiosperms. In angiosperms, pollen is produced by the anther, which sits on the filament in the center of the flower. Look closely and you will most certainly see the fine yellow powder on each anther.In order to complete fertilization, pollen must make its way to another plant.ollen grains are microscopic structures that carry the male reproductive cell of plants. The inside of the grain contains cytoplasm along with the tube cell (which becomes the pollen tube) and the generative cell (which releases the sperm nuclei).
