Biology Question on The Tissue System
Vascular cambium of stem is :
A
partly primary and partly secondary meristem
B
primary meristem
C
secondary meristem
D
intercalary meristem
Answer
partly primary and partly secondary meristem
Explanation
Solution
The primary meristem is primary in origin while the secondary meristem is secondary in origin. There is no place for vascular cambium as it is primary in origin (developing from the procambium) and secondary in function (because it forms secondary xylem, secondary phloem and secondary medullary rays).
