Mesophyll cells of leaf and additional procambial bundles also originate from ground meristem. The protoderm is the primary meristem that produces the epidermis. The outermost layer is the protoderm, which differentiates into the epidermis, then comes the procambium, which gives rise to the primary vascular tissues (primary xylem and primary phloem), and finally the ground meristem, precursor of ground tissues (parenchyma, collenchyma and sclerenchyma). They can develop to become one of three primary meristems: the protoderm, ground meristem, or procambium. by smaller cells and longer than the ground meristem, gives rise to primary vascular tissue cells (primary xylem and primary phloem) and the pericycle. In dicotyledonous stem procambium is not completely used up in the formation of primary xylem and primary phloem. The shoot apical meristem, found above ground, is composed of undifferentiated cells that have one of three destinies. Ground meristem is regarded as the precursor of fundamental or ground tissue system. see also SECONDARY MERISTEMS and MERISTEMOIDS Meristematic tissue is composed of cells whose function is to divide and make new cells.
