Which statement about secondary growth in plants is not correct?
A. Secondary growth in plants is a result of lateral meristems. Trees and shrubs have active lateral meristems.
B. Secondary growth in plants increases the girth (diameter) of woody plants.
C. Secondary growth in woody plants results from two cylinders of actively dividing cells, the cork cambium and vascular cambium.
D. The cork cambium produces secondary phloem while the vascular cambium produces secondary xylem.
E. Only some plants have secondary growth.
D. The cork cambium produces secondary phloem while the vascular cambium produces secondary xylem.
Secondary growth, which increases the diameter of a plant, occurs in some eudicots. This increase in diameter or girth, is due to the presence of lateral meristems. There are two types of lateral meristems, the cork cambium and the vascular cambium. The cork cambium contributes to the outer bark while the vascular cambium produces both secondary xylem and secondary phloem. Please read section 36.1 for more information on lateral meristems.
