Question

Which of the following is responsible for production of secondary tissues?

• A. Lateral meristem
• B. Cork cambium
• C. Interfascicular meristem
• D. All of the above

Answer 1

Answer: (D)

All of the above

Lateral meristems are usually found in woody plants and consist of vascular and cork cambium. They produce secondary tissues in the roots and stem from the vascular cambium. The cork cambium mainly replaces the epidermis in the roots and stems and thus is responsible for the secondary growth in these parts. Interfascicular meristem is a secondary meristem and during secondary growth, its derivatives are secondary phloem, secondary xylem, and conjunctive tissue.

So, the correct answer is 'All of the above'.
