Question

In monocot stem,

• A. vascular bundles are conjoint, collateral and closed
• B. secondary growth is absent
• C. phloem parenchyma is absent
• D. all the above

Answer 1

The correct option is D all the above

Vascular bundles of monocot stem are conjoint, collateral (xylem, phloem both present together on the same radius, xylem towards the inside and phloem towards outside) but closed, i.e., they lack cambium; hence secondary growth is absent. Phloem consists of sieve tubes, companion cells, and a few phloem fibers. Phloem parenchyma is absent.
