Question:
Find the statement that is NOT correct with regard to the structure of monocot stem.
Find the statement that is NOT correct with regard to the structure of monocot stem.
Show Hint
In monocot stems, the hypodermis is typically made of sclerenchyma, providing rigidity and support. Parenchyma is usually found in the ground tissue and is responsible for storage and metabolic activities.

- Vascular bundles are scattered.
- Vascular bundles are conjoint and closed.
- Phloem parenchyma is absent.
- Hypodermis is parenchymatous.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Let's evaluate each statement:
(1) Vascular bundles are scattered: This is correct. In monocot stems, vascular bundles are scattered throughout the ground tissue, unlike dicots where vascular bundles are arranged in a ring.
(2) Vascular bundles are conjoint and closed: This is also correct. In monocots, the vascular bundles are conjoint (xylem and phloem are arranged together) and closed (no cambium between xylem and phloem).
(3) Phloem parenchyma is absent: This is correct. Monocot stems generally lack phloem parenchyma, and the phloem consists mainly of sieve tubes and companion cells.
(4) Hypodermis is parenchymatous: This is NOT correct. In monocot stems, the hypodermis is usually sclerenchymatous, providing structural support, not parenchymatous.
Thus, the correct answer is "Hypodermis is parenchymatous."
