Question

Undifferentiated ground tissue is met within_____________

• A. Cucurbita stem
• B. Maize stem
• C. Pea stem
• D. Sunflower stem

Answer 1

The correct option is B Maize stem

• Cucurbita stem possess ground tissue which is well-differentiated into cortex. Cortex is also differentiated into collenchyma, chlorenchyma, and endodermis. Therefore, option A is incorrect.
• Pea is a dicotyledonous plant. Hence, it shows differentiated ground to cortex and cortex is also well differentiated.
• Therefore, option C is incorrect.
• Sunflower is a dicotyledonous plant. Hence, it shows differentiated ground to cortex and cortex is also well differentiated.
• Therefore, option D is incorrect.

Maize shows many vascular bundles scattered throughout the ground tissue, which is undifferentiated into cortex and central cylinder, as it is a monocot.

Hence, option B is correct.
