EDITORS COMMENTS
This print showcases the intricate beauty of a Nasturtium stem, captured through a scanning electron microscope (SEM). The image reveals the inner workings of this botanical wonder, with its vibrant colors and detailed structure. The freeze-fractured Nasturtium stem exhibits numerous vascular bundles that are prominently displayed at the upper center. These bundles consist of an inner xylem layer colored in pink, responsible for transporting water and minerals throughout the plant, while an outer phloem layer is depicted in yellow, which transports sugars produced during photosynthesis. With a magnification of 100 times when printed at 10 centimeters wide, this photograph allows us to explore the hidden world within plants. It provides valuable insights into plant anatomy and tissue sections by showcasing various cellular components such as parenchyma cells, spongy mesophyll layers, cuticles protecting against water loss, and epidermic structures. Nature enthusiasts and botany lovers will appreciate this stunning representation of flora's complexity. The false-colored SEM technique adds an artistic touch to scientific exploration by enhancing visual contrast and making it visually appealing. This mesmerizing image from Science Photo Library serves as a reminder of nature's remarkable intricacy while highlighting the importance of understanding plant biology for ecological studies or educational purposes.
