Which of the following statements correctly describes the vascular cambium?
A. It develops between the primary xylem and the primary phloem in dicots.
B. It occurs only in monocot stems.
C. It is important in the elongation of roots.
D. It is formed by the ground meristem.
E. It is responsible for all cell types that result from primary growth.
A. It develops between the primary xylem and the primary phloem in dicots.
Some dicots have both primary growth (initiated by apical meristems) and secondary growth (initiated by lateral meristems). There are two types of lateral meristems, cork cambium and vascular cambium. The vascular cambium initially develops between the primary phloem and primary xylem. As it produces new vascular tissue, it becomes surrounded by secondary phloem and secondary xylem. Please read section 36.1 for more information on lateral meristems.
