Solution:

a. In the monocotyledons, the vascular bundles have no cambium present in them. Hence, since they do not form secondary tissue they are referred to as closed.
b. In dicotyledons stems, cambium in present between phloem and xylem. Such vascular bundles because of the presence of cambium possess the ability to form secondary xylem and phloem tissues and hence called open vascular bundles.
