Unformatted text preview: bark tissues that break off in large scales as the tree ages. Intercalary meristem . Grasses have intercalary meristems located along the stems near the nodes. Cell divisions in this tissue push the stem upward. Grasses and other monocots have no lateral meristems so any lateral increase in size is the result of primary tissue cell enlargement, not cell divisions. Primary (transitional) meristems The cells produced by divisions in the apical meristem region are soon identifiable as three zones of distinct tissues that differentiate below the apical meristems. These are the primary meristems , called sometimes the transitional meristems: the protoderm , the procambium , and the ground meristem . They give rise to the tissue systems of the primary plant body....
