Question:
Well developed medulla is present in:
Well developed medulla is present in:
Show Hint
In standard plant anatomy MCQs, dicot roots are considered to have a well-developed pith compared to stems.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the concept of medulla (pith).
The medulla or pith is the central region of the plant axis, mainly composed of parenchymatous cells. Its development varies in roots and stems of monocots and dicots.
Step 2: Anatomy of dicot root.
In dicot roots, the central region is occupied by a well-developed pith (medulla). This region is distinct and composed of parenchyma, making it clearly visible.
Step 3: Anatomy of dicot stem.
Dicot stems also have pith, but the question specifically refers to “well developed medulla,” which is more characteristic in roots rather than stems in this context of standard exam classification.
Step 4: Anatomy of monocot root.
Monocot roots generally have a large pith, but their vascular arrangement is different and often not considered “well developed medulla” in classical comparison questions.
Step 5: Anatomy of monocot stem.
Monocot stems also have ground tissue not clearly differentiated into cortex and pith, so a true well-defined medulla is absent.
Step 6: Final evaluation.
Based on standard NCERT-based classification used in such MCQs, dicot root is considered to have a well-developed medulla.
