Branched hair in leaf stalk of water lily
False-colour scanning electron micrograph (SEM) of a branched trichome in a leaf stalk of the waterlily Nymphaea album. The waterlily has overcome the difficulty of getting air to its submerged roots by having large-diameter hollow tubes within the stalks. These tubes are connected directly to large air spaces in the leaves, which contribute to the plants buoyancy. The tubes are lined with epidermal cells & studded with trichomes. In this case, the trichome is encrusted with crystals of poisonous calcium oxalate, which probably serves to deter inquisitive burrowing insects. Magnification: x36 at 35mm size. Green tint (" leech" ). Reference: MICROCOSMOS, figure 4.17, page 75

EDITORS COMMENTS
This print showcases the intricate beauty of a water lily's leaf stalk, specifically highlighting its branched hair. Through false-color scanning electron microscopy, we are granted a closer look at the fascinating adaptations this plant has developed to thrive in its aquatic environment. The water lily, scientifically known as Nymphaea album, ingeniously overcomes the challenge of supplying air to its submerged roots by incorporating large-diameter hollow tubes within its stalks. These remarkable structures directly connect to spacious air pockets present in the leaves, contributing significantly to the plant's buoyancy. Lining these tubes are epidermal cells adorned with trichomes that add an extra layer of complexity and functionality. In this particular image, one can observe how these trichomes have become encrusted with crystals of poisonous calcium oxalate. This natural defense mechanism likely serves as a deterrent for curious burrowing insects seeking shelter or sustenance. At a magnification level of x36 at 35mm size, every detail is brought into focus. The vibrant green tint adds an ethereal quality to the photograph while emphasizing the delicate intricacies found within nature's botanical wonders. This mesmerizing image from Science Photo Library not only highlights the astonishing adaptability and resilience of plants but also serves as a reminder of their immense diversity and ability to thrive in even the most challenging environments.
