Explain the difference between primary and secondary growth
What will be an ideal response?
ANSWER: Primary growth, which is found in all vascular plants, derives from apical meristems and
results mainly in elongation of the plant in both the root and shoot systems. Secondary
growth occurs in some plants, and when it does occur, it primarily increases the girth of the
plant through growth that comes from the vascular cambium and the cork cambium.
Woody tissues are a hallmark of secondary growth.
