Cambium ring consists of
A
interfascicular cambium
B
intrafascicular cambium
C
both (a) and (b)
D
phelloderm.
Answer
both (a) and (b)
Explanation
Solution
The cambium present between xylem and phloem in the vascular bundles is called fascicular or intra fascicular cambium. Besides this, some cells of medullary rays (i.e., between vascular bundles) also become meristematic and form inter fascicular cambium. Both of these carnbia collectively constitute a complete ring of vascular cambium or intra stellar cambium. This ring. of vascular cambium or true cambium cuts off cells both on outer side and inner side. The cells cut off on outer side are secondary phloem and on inner side are secondary xylem.
