NEET Botany Secondary Growth MCQ Question
If a cambial ring in a dicot stem produces 500 secondary xylem cells and the ratio of secondary xylem to secondary phloem production is 4:1, how many secondary phloem cells are produced?
125
100
200
400
Correct Answer
Detailed Explanation
The cambial ring is more active on the inner side producing more secondary xylem than secondary phloem in a 4:1 ratio. Thus, for 500 secondary xylem cells, the secondary phloem cells produced would be 500/4 = 125.
