Dahlia flower pollen, SEM
Dahlia flower pollen. Coloured scanning electron micrograph (SEM) of a pollen grain (orange) from a Dahlia cultorum flower. A pollen grain contains a male sex cell from a flowering plant. Millions of pollen grains are produced by a flower. Some of these pollen grains are transported from a flowers anthers to the female reproductive parts of a plant, in a process called pollination. This allows the female and male sex cells to combine in the formation of a seed. Dahlias are popular garden flowers

EDITORS COMMENTS
This print showcases the intricate beauty of Dahlia flower pollen, captured through a scanning electron microscope (SEM). The vibrant orange hue of the pollen grain is visually striking against a dark background. Each grain represents a male sex cell from this particular species of flowering plant. Pollen grains play a crucial role in the reproductive process of plants. Produced in vast quantities by flowers, they are responsible for pollination - the transfer of these tiny particles from the anthers to the female reproductive organs. This enables the fusion of male and female sex cells, ultimately leading to seed formation. Dahlias, known for their stunning appearance and popularity as garden flowers, have been chosen as subjects for this scientific exploration. The spiky texture visible on each individual pollen grain adds another layer of fascination to this image. The false coloring applied to enhance certain features further highlights its biological significance. It serves as a reminder that even at such microscopic levels, nature's intricacies can be appreciated through advanced imaging techniques like SEM. This photograph is not only aesthetically pleasing but also provides valuable insights into botany and reproduction processes within plants. It stands as a testament to both the wonders found in nature and humanity's ability to capture and appreciate them through scientific exploration.
