Wood, light micrograph
Wood. Light micrograph of a transverse section through wood showing annual growth rings (near horizontal bands). A years growth consists of a porous band, which is the slow winter growth, and a more dense band, which is the faster summer growth. The Xylem vessels (large holes) are also seen in the wood. The xylem transports water and mineral nutrients from the roots throughout the plant. Its thick lignin walls also provide structural support for the stem

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of wood under a light microscope. The image captures a transverse section through wood, revealing the mesmerizing annual growth rings that form near-horizontal bands. Each year's growth is represented by two distinct bands - a porous one indicating slow winter growth and a denser band representing faster summer growth. The wood section also displays prominent xylem vessels, which are large holes responsible for transporting water and mineral nutrients throughout the plant. These vessels play a crucial role in sustaining the life of trees by facilitating essential resource distribution from roots to other parts of the plant. Moreover, this micrograph highlights how lignin, with its thick walls, provides structural support to the stem. Lignin not only contributes to the overall strength and stability of woody plants but also adds an aesthetic appeal to their appearance. By delving into such microscopic details, botanists and biologists can gain valuable insights into dendrochronology (the study of tree rings) as well as better understand various aspects related to plant biology and tissue structure. This remarkable print serves as a reminder of nature's complexity and offers us an opportunity to appreciate both its functional mechanisms and artistic patterns found within even seemingly ordinary objects like wood.
