Horsetail stem, light micrograph
Horsetail stem, light micrograph. Transverse section through the stem of the common horsetail (Equisetum arvensis). The stem consists of an outer epidermis and an outer cortex of sclerenchyma cells (dark blue) and chlorenchyma cells (pink). The inner cortex has circular air filled cavities (vallecular canals, white). In the inner vascular cylinder, a ring of vascular bundles (dark blue and red) and carinal canals (white), surround the large central canal (white). Magnification: x14 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a horsetail stem, as seen under a light microscope. The transverse section reveals the complex internal structure of this common horsetail (Equisetum arvensis). The outer part of the stem consists of an epidermis and cortex made up of sclerenchyma cells in dark blue and chlorenchyma cells in pink hues. Delving deeper into the stem, we encounter circular air-filled cavities known as vallecular canals, depicted here in white. Moving towards the center, we discover a fascinating arrangement within the vascular cylinder. A ring composed of vascular bundles is visible in shades of dark blue and red, encircling a large central canal also portrayed in white. The symmetrical nature of this cross-section highlights its botanical significance. This image provides valuable insights into plant anatomy and tissue structures that contribute to their growth and development. It serves as a reminder that even at microscopic levels, plants possess remarkable complexity. Printed at 10 centimeters wide with a magnification factor of x14, this photograph allows us to appreciate the minute details captured by light microscopy. With its white background emphasizing each element's vibrancy, it is both visually stunning and scientifically informative. This print from Science Photo Library offers an opportunity to explore the wonders hidden within our natural world while celebrating botany's diverse splendor.
