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.

In flowering plants, microspores are produced in the anthers of flowers. Each anther contains four pollen sacs, which contain the microsporocytes. After meiosis, each microspore undergoes mitotic cell division, giving rise to multicellular pollen grains (six nuclei in gymnosperms, three nuclei in flowering plants).
