About this work
Cross section through a Chrysanthemum flower bud. The stamen (male reproductive organ of a flower which produces pollen), layers forming the anther walls and developing pollen grains inside the anthers are visible here. Pollen grains contain the male gamete and are produced by the anther in a flower. They are transferred from one flower to another (pollination) so that fertilisation of the female gametes can occur (sexual plant reproduction). Pollen is a common trigger of hay fever or seasonal allergies. Width of image is 750 micrometres.
