Question

The transverse section of a plant shows following anatomical features:

 (b) Large conspicuous parenchymatous ground tissue 
 (c) Vascular bundles conjoint and closed 
 (d) Phloem parenchyma absent 
 Identify the category of plant and its part:

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Tissue Systems and their organization
	**Related Topics**: Vascular bundle arrangement, ground tissue, monocot vs. dicot anatomy
	**Prerequisites**: Basic knowledge of plant anatomy, differences between monocot and dicot stems and roots
## SOLUTION PATHWAY
**Given Information**:
	* Scattered vascular bundles with bundle sheath
	* Large parenchymatous ground tissue
	* Conjoint and closed vascular bundles
	* Phloem parenchyma absent
**Method & Steps**:
	1.	Analyze the vascular bundle arrangement: Scattered vascular bundles are characteristic of monocot stems, not dicot stems or roots.
		Reasoning: Vascular bundles in dicot stems are arranged in a ring, while roots have a radial arrangement.
		Formula/Rule: N/A
	2.	Consider the presence of bundle sheath: Bundle sheaths are present around the vascular bundles in monocot stems.
		Working: This further reinforces the identification of a monocot stem.
		Key Point: Bundle sheaths are not a distinguishing feature of roots.
	3.	Analyze the presence of large parenchymatous ground tissue: Both monocot and dicot stems have this, so it's not a unique feature.
		Result: All the given features point towards a monocotyledonous stem.
		Verification: The absence of phloem parenchyma is also consistent with monocot stem anatomy. 
 ## OPTION ANALYSIS
[A] ✓: The features described are characteristic of a monocotyledonous stem. Scattered vascular bundles with a bundle sheath, large parenchymatous ground tissue, and conjoint closed vascular bundles are all features of monocot stems. The absence of phloem parenchyma is a more specific detail that also matches the characteristics of a monocot stem.
[B] :x: Monocot roots have a radial arrangement of vascular bundles and a pith, not scattered bundles and a bundle sheath.
[C] :x: Dicot stems have vascular bundles arranged in a ring, not scattered. They also have phloem parenchyma.
[D] :x: Dicot roots have a radial arrangement of vascular bundles, and they also have phloem parenchyma. They lack a bundle sheath.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing the arrangement of vascular bundles in stems and roots.
			[How to avoid]: Review the typical arrangement of vascular bundles for each type of plant part.
		2.[Error 2]: Not paying attention to all the given features, focusing on only one or two.
			[How to avoid]: Carefully consider all the listed characteristics in the question.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember 'scattered' = monocot stem. Radial = roots.
		2.[Memory aid]: Visualize the cross-section of a monocot stem to remember its scattered vascular bundles.
