Vascular bundles in monocotyledons are considered closed because:

Options

  1. AA bundle sheath surrounds each bundle.
  2. BCambium is absent.
  3. CThere are no vessels with perforations.
  4. DXylem is surrounded all around by phloem.

Correct answer

B. Cambium is absent.

Step-by-step solution

The vascular bundles of monocotyledonous plants do not contain a layer of meristematic tissue (cambium) as the dicots do. Thus, no new cells can be formed inside the vascular bundles of monocots and their vascular bundles are termed closed whereas those of dicot plants are open.
