Root tips produce substances that make roots grow down. Plant roots are responsible for nutrient and water uptake and provide physical support to the plant. Eventually covered over by layers of wood, pith is the remains of a primary tissue formed as a twig elongates. The root cap cells are derived from the rootcap meristem that pushes cells forward into the cap region. c. Water potential decreases from the roots to the top of the plant.

Direct Pulp Caps. These small fibers are individually called the hyphae. The cap is a unique feature of roots; the tip of the stem has no such structure. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells. The rapidly dividing cells can be described as "meristematic." The root cap is a cup-shaped, loosely cemented mass of parenchyma cells that covers the tip of the root. Root Tip: the end 1 cm of a root contains young tissues that are divided into the root cap, quiescent center, and the subapical region.

Root caps contain statocytes which are involved in gravity perception in plants. As the cells of the root cap are destroyed and sloughed off, new parenchyma cells are added by a special internal layer of meristematic cells called the calyptrogen. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation. This allows the plant to grow downwards (with gravity) or upwards (against gravity). Root hairs are small thread-like structures that help the root absorb water and minerals from the soil. Transpiration draws water from the leaf. d. Water enters the plants through root hairs and exits through stoma.
