Bamboo Stem Anatomy. The bamboo stem (or culm) is the most utilized part of the bamboo plant, and consists of 3 parts:he upper one is called stem ring, which is a scar formed after the growth-cease of internode tissue. The part between the rings is the node itself. Bamboo internodes are usually hollow inside and form bamboo cavities.
In the root, the xylem (stained green-blue in the photo) are arranged. in some sort of star or cross-shape. The phloem tissue are arranged in. smaller groups in between each spike of the xylem cross-shape. Around the bundle is a special layer of cells called the endodermis. This has. a key role in getting water to the xylem vessels. Inside the endodermis is a. layer of meristem cells called the pericycle. The vascular bundles are found near the outer edge in. the stem. The xylem is found towards the inside of. each vascular bundle (see the diagram), and the. phloem towards the outside. In between the xylem and the phloem vessels there is a layer of cambium. This is a layer of meristem cells which can divide to produce more phloem or xylem. The diagram to the right (top) shows a vascular bundle in close detail. The below diagram shows a transverse section of a stem, where you can see the entire outer ring
