These grains are usually released from the male cones or anthers of flowering plants and carried by wind, water, or pollinators to fertilize ovules of female gametes. pollen plays a crucial role in plant reproduction and is a food source for various organisms. However, it can also be a primary allergen, causing respiratory issues in sensitive individuals.
