Question

Intrafascicular cambium is situated

• A. In between the vascular bundles
• B. Inside the vascular bundles
• C. Outside the vascular bundles
• D. In pith

Answer 1

The correct option is B Inside the vascular bundles

Intrafascicular cambium is primary meristem. It develops from the procambium of the stem apex. It is located inside the open vascular bundles, between phloem and xylem patches. During secondary growth the derivatives are only secondary phloem and secondary xylem. So, intrafascicular cambium is situated inside the vascular bundles.

Interfascicular cambium is secondary meristem. It develops from the parenchymatous cells of medullary rays. It is located between two consecutive vascular bundles. During secondary growth its derivatives are secondary phloem, secondary xylem and conjunctive tissue. Thus, option B is the correct answer.
