Ultimately, though, the rubber tree’s distinctive foliage offers its own unique aesthetic appeal, making it a popular choice for indoor gardeners.
Imagine a concentric circle pattern. The outermost layer is the bark, relatively thick and rough in mature trees. Beneath the bark lies the phloem, a thin layer responsible for transporting sugars produced during photosynthesis. Next, we find the cambium, a vital layer of actively dividing cells responsible for the growth of both the phloem and the xylem.
The xylem, the largest part of the cross-section, is composed of woody tissue, forming the bulk of the trunk and providing structural support. The innermost layer is the heartwood, the oldest xylem tissue, which is darker in color and generally less active in water transport. The various layers work in concert, supporting the tree’s life functions and its remarkable ability to produce latex.
