Vascular bundles in monocotyledons are considered closed because
a bundle sheath surrounds each bundle
cambium is absent
there are no vessels with perforations
there are no vessels with perforations
B.
cambium is absent
The vascular bundles of monocots do not contain a layer of meristematic tissue (cambium). There is absence of meristematic tissue near vascular bundles, therefore vascular system is closed in monocot. Hence, the further secondary growth is not seen in them.
So, option (b) goes with question.
Which one of the following is not an inclusion body found in prokaryotes?
Phosphate granule
Cyanophycean granule
Glycogen granule
Glycogen granule
Which one of the following human organs is often called the “graveyard” of RBCs?
Gall bladder
kidney
Spleen

A major characteristic of the monocot root is the presence of
Open vascular bundles
Scattered vascular bundles
Vasculature without cambium
