Which tissue is not correctly related to its fate during the secondary growth?

Options

  1. ATissue Fate during secondary growth Secondary xylem Produced in high amount
  2. BTissue Fate during secondary growth Primary phloem Produced in low amount
  3. CTissue Fate during secondary growth Cambial ring Cut off secondary permanent tissue on both side
  4. DTissue Fate during secondary growth Secondary phloem Synthesized on outer side

Correct answer

B. Tissue Fate during secondary growth Primary phloem Produced in low amount

Step-by-step solution

Mechanism in secondary growth in vascular region of dicot stem 1 . Vascular cambium (intrafscicular cambium) alongwith interfascicular cambium forms a continuous ring of cambium. 2 . Cambial ring becomes active and cut off secondary phloem towards outer side and secondary xylem towards inner side. 3 . Secondary xylem is produced more in quantity as cambium is more active in its inner part. 4 . When secondary growth repeats few more times, high amount of secondary xylem is accumulates which results in crushing of th
