Cedar pollen, SEM
Cedar pollen. Coloured scanning electron micrograph (SEM) of pollen grains from a cedar tree. The characteristic outer wall, or exine, of pollen grains is used by botanists to recognise and classify plants. Each pollen grain contains a male gamete (sex cell) that is intended to fertilise an egg or ovule (female gamete) and initiate the formation of a seed for a new plant. These pollen grains are an allergen that may cause hay fever in susceptible individuals

EDITORS COMMENTS
This print captures the intricate beauty of cedar pollen under a scanning electron microscope (SEM). The false-colored image showcases the characteristic outer wall, or exine, of these pollen grains, which is crucial for botanists in identifying and classifying plants. Each grain contains a male gamete, or sex cell, that plays a vital role in fertilizing an egg or ovule to initiate seed formation and give birth to new plant life. However, while these pollen grains hold the promise of reproduction and growth, they also serve as allergens that can trigger hay fever in susceptible individuals. This dual nature adds complexity to their significance in nature's grand tapestry. The vibrant colors and sculpted contours of this SEM image highlight the biological intricacies within each grain. It serves as a reminder of the incredible diversity found within our botanical world – from evergreen giants like cedars to delicate wildflowers. As we delve into this microscopic realm through scientific advancements such as SEM technology, we gain deeper insights into how plants disperse their genetic material and perpetuate their existence. This mesmerizing photograph not only celebrates the wonders of biology but also reminds us of our interconnectedness with nature's cycles.
