Section through Yew wood
Light micrograph of a radial longitudinal section through the wood (secondary xylem) of the Yew tree, Taxus baccata, showing the vertical, tube- like structures known as tracheids. In softwoods, like yew, these carry out both sap-conducting and mechanical functions. Dark hair-like spirals of secondary thickening are visible on the walls of the tracheids. These serve to strengthen the cell walls. They are laid down while the xylem is still elongating and the spiral pattern allows the cells to stretch longitudinally. The white dots are holes known as pits. They allow sap to flow between adjacent cells. Magnification: x200 at 35mm size

EDITORS COMMENTS
This print offers a mesmerizing glimpse into the intricate world of yew wood. A radial longitudinal section through the secondary xylem of a Taxus baccata, or Yew tree, reveals an awe-inspiring network of vertical tube-like structures called tracheids. In softwoods like yew, these remarkable tracheids serve dual purposes as conduits for sap and mechanical support. Upon closer examination, one can observe dark hair-like spirals adorning the walls of these tracheids. These striking patterns are known as secondary thickening and play a crucial role in fortifying the cell walls. Fascinatingly, these spirals are formed while the xylem is still elongating, allowing flexibility and stretching along their longitudinal axis. The white dots scattered throughout this micrograph are aptly named pits – tiny holes that facilitate sap flow between adjacent cells. They represent nature's ingenious plumbing system within plants. Magnified at 200 times its original size on a 35mm scale, this image captures both the scientific beauty and complexity found within plant anatomy. It serves as a testament to Nature's ingenuity and showcases how even seemingly simple elements like wood possess extraordinary intricacies when observed under microscopic lenses. This stunning photograph from Science Photo Library invites us to appreciate the wonders hidden within our natural surroundings while shedding light on botanical marvels such as taxus baccata and its remarkable softwood composition.
