Meristematic tissue is located in the apical meristems at the growing points of roots and stems, the secondary meristems (lateral buds) at the nodes of stems (where branching occurs), and meristematic tissue, called the cambium, that is found within mature stems and roots. The meristems also influence the shapes of the mature plants since the patterns for subsequent growth are laid down in the meristems. Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).
