Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
Which lateral meristem produces wood and inner bark?
B. Vascular cambium
The vascular cambium adds secondary xylem inward and phloem outward. The cork cambium forms periderm; apical meristems give length; intercalary meristems add length at internode bases.
