Beech tree leaf, light micrograph
Beech tree leaf. Light micrograph of a section through the leaf of a common beech tree (Fagus sylvatica), showing the midrib. The midrib has at its centre a horseshoe of vascular bundles, the xylem (red files) is inward and the phloem (brown) is outward. Around the vascular ring is a thick ring of supportive sclerenchyma tissue (deep red) with the ground tissue parenchyma (light brown) surrounding it. Under the two epidermis layers is a flexible supporting collenchyma tissue (red-brown). The leaf lamina has one palisade mesophyll layer (deep red) on top of a lower spongy mesophyll layer (red). The lower epidermis contains stomata (pores). Magnification: x37, when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate details of a beech tree leaf, captured through a light micrograph. The image reveals the fascinating structure of the leaf, particularly focusing on its midrib. At the center of this midrib lies a horseshoe-shaped arrangement of vascular bundles, with the xylem appearing as vibrant red filaments inward and phloem as brown strands outward. Surrounding this vascular ring is a thick layer of supportive sclerenchyma tissue, depicted in deep red hues. Encircling it further is the ground tissue parenchyma, portrayed in lighter shades of brown. Beneath two layers of epidermis lies flexible supporting collenchyma tissue in reddish-brown tones. The leaf lamina exhibits an intriguing composition consisting of one palisade mesophyll layer in deep red atop a lower spongy mesophyll layer represented by vivid red shades. Notably, the lower epidermis contains stomata or pores that facilitate gas exchange. With a magnification factor of x37 when printed at 10 centimeters wide, this stunning image offers viewers an up-close look into the cellular and structural intricacies within plant biology. It provides valuable insights into botany and histology while highlighting key features such as cell walls, tissues, and various structures present within dicotyledonous plants like common beech (Fagus sylvatica). This remarkable photograph serves as both an educational tool for biologists and an aesthetically pleasing piece for nature enthusiasts to appreciate.
