Solution
The correct option is B Open
The vascular bundles of dicot plants have a layer of meristematic tissue called cambium present inside them and these cells can divide, causing an increase in size. Hence they are called Open bundles.
Monocot vascular bundles do not possess cambium and hence no growth occurs. Hence they are called Closed bundles.
In collateral vascular bundles xylem remains towards the inner side and phloem towards the outer side.
In Conjoint vascular bundles , xylem and phloem tissues are present on the same radius.
