Show Answer

Answer:

Correct Answer: B

Solution:

  • In monocotyledons, the vascular bundles are considered closed because they lack a cambium layer, which means they do not have the ability to undergo secondary growth (increase in thickness). This is in contrast to dicotyledons, which typically have an open vascular system with a cambium layer that allows for secondary growth.
