Pollen is a fine powder produced by the male reproductive organs of flowering plants, known as anthers. It contains the male gametes, or sperm cells, necessary for fertilizing the female ovules in flowers. Pollen is essential for the reproduction of many plants, as it allows for the transfer of genetic material between different individuals, promoting biodiversity. In addition to its role in plant reproduction, pollen is also a crucial food source for many insects, particularly bees. These insects collect pollen to feed their young and to produce honey. Pollen can also be a common allergen for humans, causing allergic reactions in some individuals during certain seasons.
