Example text

The primary xylem of monocots, on the other hand, forms a cylinder around a central mass of pith parenchyma, a siphonostele. The way in which the vascular tissues develop is useful in tracing ancestral relationships in the plant kingdom. Secondary Growth of Roots Secondary tissues comprise the greatest volume of the root mass of woody perennial plants. Primary tissues continue to form in the feeder roots, but the supporting root structure consists of secondary tissues produced by the lateral meristems, the vascular cambium, and one or more cork cambia.

Hemicelluloses and pectins are deposited among the fibril network and chemically bind the whole together. The result is a primary wall. The whole process of synthesis and assembly is coordinated by the plasma membrane. Lignin, the second most common material of plant cell walls, adds additional strength to cells, such as in wood cells. Other substances are deposited in walls of tissues serving particular functions. F 12/21/00 4:03 PM Page 24 CELLS both of which effectively reduce the loss of water from the leaves.

Between the area of active division and the cap is an area where cells divide more slowly, the quiescent center. Most cell divisions occur along the edges of this center and give rise to columns of cells arranged parallel to the root axis. The parenchyma cells of the meristem are small, cuboidal, with dense protoplasts devoid of vacuoles and with relatively large nuclei. The apical meristem of the root organizes to form the three primary meristems: protoderm, which gives rise to the epidermis; procambium, which produces xylem and phloem; and the ground meristem, which produces the cortex.
