Type: MCQ-numerical-Hard-Class 11
If the cambial ring in a dicot root produces 50 units of secondary xylem towards the pith, how many units of secondary phloem are likely produced towards the periphery, given the cambium is more active on the inner side?
A
20 units
B
25 units
C
30 units
D
35 units
Correct Answer
Option B
Detailed Explanation
The cambium is more active on the inner side, producing more secondary xylem. If 50 units of xylem are produced, typically less phloem is produced. Assuming a 2:1 ratio, approximately 25 units of phloem are produced.
