Question

Select the correct option:

During the secondary growth in a dicotyledonous stem, the fusiform initials of vascular cambium give rise to

• A. Secondary xylem
• B. Secondary phloem
• C. Medullary ray
• D. Both A and B

Answer 1

The correct option is D Both A and B

During secondary growth in a dicotyledonous stem the fusiform initials of vascular cambium gives rise to both the secondary xylem cells as well as the secondary phloem cells. Secondary medullary rays are produced by the vascular cambium and terminate at the xylem or phloem.

Thus, the correct answer is 'both (a) and (b).'
