African teak woody stem, light micrograph
African teak woody stem. Polarised light micrograph of a section through the stem of an African teak (Pericopsis elata) plant, showing its diffuse-porous xylem tissue. The xylem vessels (vertical, dark blue), which carry most of the water, are scattered throughout the xylem tissue. Some of the vessels walls can be seen. These have a network of perforation pits that let water sideways if there is a blockage in the vessel. The multicoloured longitudinal cells are fibres, and fibre tracheids. Medullary rays can also be seen (blackish). Magnification: x6 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of an African teak woody stem, captured through a polarised light micrograph. The image reveals a section of the stem, highlighting its diffuse-porous xylem tissue. Within this tissue, scattered throughout like a network of veins, are the dark blue xylem vessels responsible for transporting water throughout the plant. The walls of these vessels display a fascinating pattern of perforation pits that serve as emergency exits for water in case of blockages. Surrounding the vessels are multicoloured longitudinal cells known as fibres and fibre tracheids, which provide structural support to the stem. Additionally, medullary rays can be observed in blackish hues. With a magnification factor of six when printed at 10 centimetres wide, this image allows us to appreciate the intricate details and complexity present within nature's design. It offers insight into the cellular composition and transport system found within angiosperms like Pericopsis elata. This stunning visual representation not only serves as an artistic marvel but also provides valuable information to researchers studying botany, biology, histology, and cell biology. Through microscopy techniques such as staining and polarised light imaging, scientists gain deeper understanding about plant structures and their functions. Science Photo Library has once again delivered an awe-inspiring piece that highlights both scientific exploration and aesthetic appreciation for our natural world.
