Sharp rush stem, light micrograph
Sharp rush stem. Light micrograph of a section through the stem of a sharp rush (Juncus acutus) plant. This arid-adapted plant (xerophyte) has scattered vascular bundles. From the outer to the inner layer: thick-celled silicified epidermis (pink) covered with a thick cuticle (brown-green); triangular patches of fibres in-between which is columnar palisade tissue containing chloroplasts (blackish-brown); thick-walled parenchyma tissue (hexagonal); thin-walled parenchyma tissue containing oval vascular bundles; supporting fibres (whitish-pink); phloem (blue); xylem (pink-yellow). Magnification: x37 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate structure of a sharp rush stem, revealing its remarkable adaptations to arid environments. The light micrograph provides a detailed view of a cross-section through the stem, offering insights into the plant's cellular composition. The outermost layer is composed of thick-celled silicified epidermis, which appears in a striking pink hue and is protected by a robust brown-green cuticle. Moving inward, triangular patches of fibers can be observed interspersed with columnar palisade tissue containing chloroplasts that give off a blackish-brown coloration. Further inside, we encounter thick-walled parenchyma tissue arranged in hexagonal patterns. Within this layer lies thin-walled parenchyma tissue housing oval vascular bundles. Supporting fibers are also visible in whitish-pink shades. As we delve deeper into the stem's structure, distinct regions become apparent: phloem depicted in soothing blue tones and xylem exhibiting vibrant pink-yellow hues. This image not only highlights the complexity and diversity within plant tissues but also emphasizes how sharp rushes have evolved specialized features to thrive in harsh desert conditions as xerophytes. With scattered vascular bundles and an array of cell types strategically organized for optimal function, these plants exemplify nature's ingenuity at adapting to challenging environments. Captured at 37 times magnification when printed 10 centimeters wide, this stunning micrograph invites us to appreciate the hidden beauty found within botanical structures while shedding light on essential aspects of botany and biology.
