| Description |
cross section: Young herbaceous dicot Ranunculus common name: Buttercup magnification: 100x <a href="http://blogs.berkshirecc.edu/bccoer" rel="nofollow">Berkshire Community College Bioscience Image Library</a> The single layered epidermis lacks any significant cuticle. Root hairs appear as unicellular extensions of epidermal cells. The cortex in younger roots is composed of loosely packed parenchyma cells. The inmost area of the cortex is bounded by an endodermis or starch sheath with larger barrel shaped cells and thickened walls that mark the casparian strip. Within the endodermis occasional small passage cells serve to transport of water into the stele or vascular bundle. The stele is bound on its outmost edge by is a pericycle of single layered thin walled parenchyma cells. The closed vascular bundles are arranged radially with arms of exarch xylem interspaced with patches of phloem and parenchymous conjunctive tissue. These tissues may become sclerenchymous in older roots Vascular cambium is also absent, preventing secondary growth of the root. |
