Beech tree stem, light micrograph
Beech tree stem. Polarised light micrograph of a section through the woody stem of a common beech tree (Fagus sylvatica), showing diffuse-porous xylem vessels (dark blue) scattered throughout the tissue. Some of the vessels show the vessel walls, which have a network of bordered pits that let water travel sideways if there is a blockage. The multicoloured longitudinal cells are fibres, and fibre tracheids. The horizontal files are the medullary rays, which carry water, minerals and food to the outer and inner tissues. Magnification: x7, when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate structure of a beech tree stem, as seen under polarised light microscopy. The image reveals the complex network of diffuse-porous xylem vessels, depicted in a striking dark blue hue and dispersed throughout the tissue. These vessels play a vital role in transporting water and nutrients within the plant. The vessel walls are highlighted, exhibiting a fascinating arrangement of bordered pits that enable lateral movement of water in case of blockages. The vibrant multicoloured longitudinal cells represent fibres and fibre tracheids, contributing to the strength and support of the stem. Notably, the horizontal files visible in this micrograph are known as medullary rays. These rays serve as conduits for essential substances such as water, minerals, and food between outer and inner tissues. With a magnification factor of x7 when printed at 10 centimetres wide, this image offers an up-close look into the biological wonders found within plants. It provides valuable insights into botany, cell biology, cytology, histology, and more. This extraordinary photograph is part of Science Photo Library's collection dedicated to capturing scientific marvels with stunning detail. It serves as a testament to nature's complexity while showcasing its beauty through scientific exploration.
