  2. In monocotyledonous plants, vascular bundles are closed type.
  3. Thus, cambium is absent between xylem and phloem, due to which secondary growth does not occur in these plants.
  4. Increase in girth of a stem occurs by secondary growth. Thus, the girth of a maize plant does not increase over a period of time.
