Solution
- Maize plant belongs to class monocotyledonae.
- In monocotyledonous plants, vascular bundles are closed type.
- Thus, cambium is absent between xylem and phloem, due to which secondary growth does not occur in these plants.
- 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.
