Pea flower pollination, SEM

Pea flower pollination. Coloured scanning electron micrograph (SEM) of pollen grains (yellow) on the stigma (green) of a garden pea flower (Pisum sativum). The pollen grains, which contain male genetic material, have become trapped by the stigmas papillae (hair-like structures, green). The stigma is part of the female reproductive structure (pistil), which is formed from one or more carpels. Each carpel consists of a stigma, a style and an ovary (not seen). If the female sex cells (ovules) in the ovary become fertilised by the pollen grains male sex cells, the carpel may ripen to produce a fruit containing seeds. Magnification: x180 at 6x7cm size

EDITORS COMMENTS
This print captures the intricate process of pea flower pollination. In this coloured scanning electron micrograph (SEM), we witness the delicate dance between male and female genetic material. The vibrant yellow pollen grains can be seen adorning the green stigma of a garden pea flower, scientifically known as Pisum sativum. The stigmas papillae, hair-like structures in green, play a crucial role in this reproductive ballet by trapping the pollen grains. The stigma is part of the pistil, which is formed from one or more carpels. Each carpel consists of a stigma, style, and ovary (not visible in this image). If fertilization occurs between the male sex cells contained within the pollen grains and the female sex cells (ovules) housed within the ovary, then magic happens. The carpel may ripen to produce a fruit that contains seeds. This mesmerizing SEM image magnified at x180 showcases nature's remarkable complexity on a minuscule scale. It offers us an opportunity to appreciate both structure and beauty simultaneously while shedding light on essential botanical processes such as pollination. Science Photo Library has once again provided us with an awe-inspiring glimpse into our natural world through their exceptional photography skills and scientific expertise.
