Pollen magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anther of a flower to the stigma of the same flower. Pollen itself is not the male gamete. Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive)
Shroud of Turin in Edessa, Turkey. Mark Antonacci argues that the pollen evidence and flower images are inherently interwoven and strengthen each other. However it was subsequently determined that Baruch's work was "scientifically unsafe", and Danin thereafter disowned the publication of this work. Danin stated in 2011, that: "In 2001 we brought most of the slides to Prof. Dr. Thomas Litt who is an expert palynologist and has very sophisticated microscopic equipment. Prof. Litt concluded that none of the pollen grains he saw could be named at a species level. Hence, all the conclusions drawn from previous palynological investigations of Dr. Frei's material
