Lime tree stem wound, light micrograph
Lime tree stem wound. Light micrograph of a section through the wounded stem of a lime tree (Tilia europaea). The outer epidermis has been shed and replaced by a layer of cork (dark red). At this point there has been a wound so the meristem (blue with red nuclei) has produced a layer of new cells. The periderm has then laid down outer layers of cork to plug the hole to stop the ingress of fungi, bacteria and insects. Magnification: x37 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases a close-up view of a lime tree stem wound, revealing the intricate cellular structures and processes involved in its healing. The image, taken under a light microscope, provides an extraordinary level of detail. The outer epidermis of the wounded stem has been shed and replaced by a layer of cork, depicted here in dark red. This protective cork layer serves as a barrier against harmful external agents such as fungi, bacteria, and insects. At the site of the wound, the meristem – represented by blue with red nuclei – has generated new cells to facilitate repair. The periderm, responsible for secondary growth in plants' stems and roots, then deposits additional layers of cork to seal off the hole completely. This sealing mechanism prevents further damage or infection from reaching deeper into the plant's tissues. With a magnification factor of x37 when printed at 10 centimeters wide, this micrograph allows us to appreciate both the complexity and beauty found within nature's smallest details. It offers insights into botany, biology, cytology (the study of cells), histology (the study of tissues), and angiosperm anatomy (flowering plants). By capturing this moment in time through scientific photography expertise provided by Science Photo Library - not just any company - we are able to explore these fascinating aspects without commercial intentions.
