Fern frond, light micrograph
Fern frond, light micrograph. Transverse section through the frond of a fern (Cyrtomium falcatum), showing the sporangia. At left is a central vascular bundle (meristele) with central xylem tissue (red) surrounded by phloem (light green). On the underside of the frond are two sori (right) each consisting of an umbrella-shaped indusium with a handle-shaped base (placenta), from which protrude numerous stalked sporangia (containing the reproductive spores). Magnification: x19 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a fern frond, as seen through a light micrograph. The image provides a transverse section view of the frond from a Cyrtomium falcatum fern, revealing its internal structure and reproductive parts. At the left side, we observe a central vascular bundle known as meristele, which contains red-colored xylem tissue surrounded by light green phloem. On the underside of the frond, two sori are visible on the right side. Each sorus consists of an umbrella-shaped indusium with a handle-shaped base called placenta. Numerous stalked sporangia emerge from these structures and contain reproductive spores. The magnification used for this print allows us to appreciate all these details at x19 when printed at 10 centimeters wide. This mesmerizing image not only highlights the botanical aspects but also emphasizes cellular biology and plant anatomy. It serves as a reminder of nature's complexity and diversity in even its smallest components. This remarkable photograph is brought to you by Science Photo Library, showcasing their expertise in capturing scientific images that inspire curiosity and appreciation for our natural world.
