NEET Botany Secondary Growth MCQ Question
During secondary growth in a dicot stem, the cambial ring produces more secondary xylem on the inner side than secondary phloem on the outer side. If the cambial ring produces 1500 cells in a season, and the ratio of secondary xylem to secondary phloem cells produced is 3:1, how many secondary phloem cells are produced?
375
500
750
1125
Correct Answer
Detailed Explanation
The cambial ring produces cells in a 3:1 ratio of secondary xylem to secondary phloem. Therefore, out of 1500 cells, 1/4 are secondary phloem cells (1500/4 = 375).
