Pollen grain of a German chamomile flower
Chamomile pollen. Coloured scanning electron micrograph (SEM) of a single tricolporate pollen grain from a German chamomile flower, Matricaria recutita. Pollen grains are the male sexual spores that are discharged from the male part of the flower. They contain the gamete that fertilizes the female ovule to form a seed. This pollen has 3 furrows from each of which protrudes a bulge or pore (light brown) and is thus classified as tricolporate". German chamomile relies on insects to carry the pollen to another flower. The spikes (orange) help the pollen grain to attach itself to an insect for this purpose. Magnification: x2000 at 6x6cm size Magnification: x4000 at 5x5" size."

EDITORS COMMENTS
This print showcases the intricate beauty of a pollen grain from a German chamomile flower. The coloured scanning electron micrograph (SEM) reveals the remarkable details of this tricolporate pollen grain, originating from Matricaria recutita. These grains serve as male sexual spores that are released from the flower's male part and contain gametes responsible for fertilizing female ovules to form seeds. What makes this particular pollen unique is its classification as tricolporate, denoting three furrows, each with a protruding bulge or pore in light brown coloration. This structural feature aids in identifying and distinguishing it within the botanical realm. German chamomile relies on insects for pollination, and the orange spikes visible in the image play a crucial role in facilitating this process. By attaching themselves to insects, these spikes ensure efficient transportation of pollen between flowers. The magnified view at 2000x at 6x6cm size and 4000x at 5x5" size allows us to appreciate nature's microscopic wonders up close. This photograph not only highlights the importance of reproductive mechanisms in plants but also serves as a testament to their extraordinary adaptability and evolution over time. Captured by Science Photo Library, this image encapsulates both scientific curiosity and aesthetic appreciation for botany enthusiasts worldwide.
