Timothy grass pollen grains
Timothy grass pollen. Coloured scanning electron micrograph (SEM) of a pollen grain from Timothy grass, Phelum pratense, also known as cat s-tail. This pollen is very light with a smooth outer wall (exine); both features assist wind dispersal. Each Timothy grass pollen grain possesses a single pore (seen here) which facilitates germination of the pollen. It may also be involved in water regulation and control of compatibility between the pollen and stigma of the pollinated flower. Timothy grass flowers in the summer and its pollen is a major cause of hay fever (allergic rhinitis and pollenosis). Magnification: x 1, 150 at 5x7cm size. x3900 at 10x8ins

EDITORS COMMENTS
This print showcases the intricate beauty of Timothy grass pollen grains. Under the lens of a scanning electron microscope, these tiny grains reveal their unique features that aid in wind dispersal. The smooth outer wall, known as exine, and lightweight nature make them easily carried by even the slightest breeze. Each Timothy grass pollen grain possesses a single pore, visible in this image, which serves multiple purposes. It not only facilitates germination but also plays a role in water regulation and controls compatibility between the pollen and stigma of pollinated flowers. Timothy grass is notorious for causing hay fever during summer months due to its abundant release of pollen. Allergic rhinitis and pollenosis are common reactions triggered by this specific type of plant reproductive material. With a magnification level of x1,150 at 5x7cm size or x3,900 at 10x8ins size, this photograph allows us to appreciate the intricate details that often go unnoticed by the naked eye. Through scientific exploration and visual representation like this stunning print from Science Photo Library, we gain deeper insights into the fascinating world of nature's reproductive mechanisms and their impact on our daily lives.
