But of course in addition to lengthening, some roots and shoots eventually also increase in girth and become woody. There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem). The lateral meristem is present in the sides of stem and roots and the intercalary meristem is present between the tip and the base of the stem and leaves. plant development: The activity of meristems.
