NEET Botany Secondary Growth MCQ Question
During secondary growth in dicot stems, the cambial ring primarily produces more secondary xylem than secondary phloem. If the cambial activity results in the production of 8 units of secondary xylem, how many units of secondary phloem are likely to be produced?
2 units
4 units
6 units
8 units
Correct Answer
Detailed Explanation
The NCERT text states that the cambium is generally more active on the inner side than on the outer, resulting in more secondary xylem than secondary phloem. A typical ratio would be 2:1, so with 8 units of xylem, 4 units of phloem are expected.
