Liana stem, light micrograph
Liana stem. Light micrograph of a transverse section through the stem of a liana (Aristolochia tormentosa), or woody vine. At the centre of the stem is the pith, consisting of parenchyma cells. Around this is a ring of vascular bundles. Each bundle contains phloem (red) and xylem (purple) cells, which transport carbohydrates and water around the plant respectively. Outside of these is the cortex, which is also made of parenchyma cells and contains a ring of thick walled sclerenchyma cells (purple) that provide structural support. Magnification: x45 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a liana stem, captured through a light micrograph. The transverse section reveals the inner structure of this woody vine, providing a glimpse into its remarkable anatomy. At the core of the stem lies the pith, composed of parenchyma cells that serve various functions within the plant. Surrounding it are vascular bundles forming a ring-like pattern. These bundles play a crucial role in transporting carbohydrates and water throughout the liana via phloem (depicted in red) and xylem (shown in purple) cells respectively. Moving outward from these vital transport systems is the cortex, also comprised of parenchyma cells. However, what catches one's attention are the thick-walled sclerenchyma cells depicted in purple. These robust structures provide essential support to ensure stability for this climbing plant as it reaches towards sunlight. The magnification level employed for this print allows viewers to appreciate every intricate detail at 10 centimeters wide. Against a white background, this image truly highlights nature's wonders and offers valuable insights into botany and plant biology. With its meticulous depiction of liana stem anatomy, this print serves as an invaluable resource for researchers or enthusiasts interested in exploring plant anatomy or studying climbing plants like Aristolochia tormentosa – commonly known as lianas – which possess unique adaptations enabling them to thrive amidst their lush surroundings.
