Waterweed stem, light micrograph
Waterweed stem. Polarised light micrograph of a transverse section through a stem of the aquatic western waterweed (Elodea nuttallii) plant. All aquatic plants (hydrophytes) have a similar stem structure. The epidermis (outer layer) has a thin cuticle that is permeable to water. The cortex is very wide and the parenchyma has large air spaces (lacunae, white spaces). This plant has an outer endodermis (ring of small blue cells) under which is a ring of phloem (blue and purple cells) and an inner single layered ring of xylem, around a central canal. Magnification: x103 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a waterweed stem, captured under polarised light micrograph. The image depicts a transverse section through the stem of the aquatic western waterweed (Elodea nuttallii) plant, offering a glimpse into the fascinating structure shared by all hydrophytes. The outer layer, known as the epidermis, is adorned with a delicate and permeable cuticle that allows for efficient water absorption. Moving inward, we encounter an expansive cortex accompanied by large air spaces or lacunae represented as white spaces in this visual masterpiece. Notably, this particular plant exhibits an outer endodermis composed of small blue cells followed by a ring of phloem cells in shades of blue and purple. Nestled within lies an inner single-layered ring of xylem surrounding a central canal. With its magnification at x103 when printed 10 centimeters wide, every detail is meticulously preserved to offer viewers an immersive experience into the world of botany. This print serves as both educational support and artistic inspiration for those fascinated by nature's wonders. Immerse yourself in this stunning portrayal that seamlessly merges science and artistry—a testament to Science Photo Library's commitment to capturing awe-inspiring moments from our natural world without commercial intent.
