Question

Which of the following is correct with regard to monocot stem?

• A. Monocot stems have a well-developed collenchymatous hypodermis.
• B. The vascular bundles are surrounded by a sclerenchymatous bundle sheath.
• C. The cortex is differentiated into endodermis and pericycle.
• D. The vascular bundles are conjoint and open.

Answer 1

Answer: (B)

The monocot stem has a sclerenchymatous hypodermis, a large number of scattered vascular bundles, each surrounded by a sclerenchymatous bundle sheath, and a large, conspicuous parenchymatous ground tissue. It doesn't have pericycle. Vascular bundles are conjoint and closed. Peripheral vascular bundles are generally smaller than the centrally located ones.
