Leaf stem node, light micrograph
Leaf stem node. Light micrograph of a vertical section through a leaf stem node from a sycamore tree (Acer pseudoplatanus). The node (centre) has two leaf stems (petioles) branching off at upper left and right. This image shows the formation of cork (phellogen layer, red), and the abscission layer (green) that forms at the base of the petioles prior to the leaves falling from the plant in the autumn

Acer Pseudoplatanus Autumn Autumnal Cork Deciduous Falling Foliage Leaf Fall Longitudinal Microscopy Petiole Phellogen Scale Shed Shedding Stems Sycamore Light Micrograph Light Microscope Section Sectioned
EDITORS COMMENTS
This print captures the intricate details of a leaf stem node from a majestic sycamore tree. The vertical section reveals the fascinating process of nature's autumnal transformation, as the leaves prepare to gracefully fall from their branches. In this image, we witness the formation of cork, represented by the vibrant red phellogen layer, which acts as a protective shield for the plant. Additionally, we can observe the abscission layer in vivid green at the base of two leaf stems (petioles), signaling their imminent detachment from the tree. Through meticulous microscopy and anatomical examination, this light micrograph showcases both the biological complexity and beauty inherent in botany. The longitudinal sectioning allows us to marvel at every minute detail - from delicate foliage scales to shed leaf buds - providing an intimate glimpse into this natural shedding process. As we delve into this botanical wonderland captured by Science Photo Library, we are reminded of how plants adapt and transform with each passing season. This image serves as a testament to nature's perpetual cycle of growth and renewal while highlighting our ability to appreciate its intricacies through scientific exploration.
