Marrow stem, light micrograph
Marrow stem. Light micrograph of a section through the stem of a marrow (Curcurbita sp.), showing the sieve plates in the phloem. A single collateral vascular bundle can be seen. This has an outer and inner phloem (blue-black) with large sieve tubes some of which show sieve plates (dotted blue) and companion cells, with an inner xylem (red) with large vessels and small woody parenchyma. The cambium (dark blue, small cells) is in-between the phloem and xylem. Surrounding the bundle is the ground tissue parenchyma (red-brown). Magnification: x37, when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases a light micrograph of a marrow stem, providing us with an intricate glimpse into the inner workings of this botanical wonder. The image reveals a section through the stem of a Curcurbita sp. , highlighting the sieve plates within the phloem. A single collateral vascular bundle takes center stage, displaying both outer and inner phloem in striking blue-black hues. The large sieve tubes are visible, some adorned with dotted blue sieve plates and accompanied by companion cells. In contrast, the inner xylem is depicted in vibrant red, featuring sizable vessels and small woody parenchyma. The cambium layer, represented by dark blue small cells, resides between the phloem and xylem, playing a crucial role in plant growth and development. Surrounding this vital vascular bundle is the ground tissue parenchyma portrayed in rich red-brown tones. With a magnification level of x37 when printed at 10 centimeters wide, this image allows us to appreciate the structural intricacies that make up these dicotyledonous plants' stems. It offers valuable insights into botany, biology, histology, cytology - all contributing to our understanding of cellular structures within plants. Captured by Science Photo Library's expert lens and stained for enhanced visibility under microscopy techniques; this remarkable print serves as an educational tool for scientists and enthusiasts alike who seek to explore nature's hidden wonders on a microscopic scale.
