Unformatted text preview: • Uniform upward diameter • Thickened parenchyma cells for support • Long lived phloem • Large apex (or tip) providing for o Leaves with large vascular connections that sheath the stem increasing the diameter of the axis Example = Palms Thickened palm meristem Uniform stem diameter in palm • Prop roots develop providing long-term support for the plant (See roots section) Example = Pandanus or corn • Produce a cambium that produces additional vascular bundles, but not a "wood". This increases volume but is not necessarily a "tree-like" organism Example = Agave • Sheath the stem with giant leaves that have extraordinary vascular tissue (vein) connections. Veins, the vascular tissue of leaves, have many sclerenchyma fibers. Often such plants are quite short-lived, although they achieve big dimensions Example = Banana...
