Question

Which of the following is a characteristic feature of sclerenchyma cells?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [Option B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Sclerenchyma cells are a type of supportive tissue in plants characterized by their thick and lignified walls.
	**Related Topics**: Plant tissues, types of cells in plants, structural support in plants.
	**Prerequisites**: Basic understanding of plant cell types and their functions.
## SOLUTION PATHWAY
**Given Information**:
		1. Sclerenchyma cells are known for their structural properties.
		2. They provide mechanical support to the plant body through their cell structure.
**Method & Steps**:
	1. Identify the key characteristics of sclerenchyma cells.
		Reasoning: Sclerenchyma cells are specialized for support and are usually dead at maturity, possessing thick walls.
		Formula/Rule: The properties of sclerenchyma include heavy lignification, which makes the walls thick and rigid.
	2. Compare the options provided in the question based on their descriptions.
		Working: Evaluate each option against the known features of sclerenchyma cells.
		Key Point: Options A, C, and D are characteristics of other cell types (parenchyma, collenchyma) rather than sclerenchyma.
	3. Conclude with the correct characteristic of sclerenchyma cells.
		Result: The thick, lignified secondary walls (Option B) are indeed characteristic of sclerenchyma cells.
		Verification: By eliminating the other options, it becomes evident that B is the only correct choice.
 ## OPTION ANALYSIS
[A] :x: Incorrect. Thin, permeable primary walls are characteristic of parenchyma cells, not sclerenchyma.
[B] ✓: Correct. Thick, lignified secondary walls are the hallmark of sclerenchyma cells, providing structural support.
[C] :x: Incorrect. Presence of large intercellular spaces is typical of parenchyma cells, allowing for gas exchange and storage.
[D] :x: Incorrect. Abundant cytoplasm is characteristic of living cells, particularly parenchyma, not the dead sclerenchyma cells.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing sclerenchyma with parenchyma: Remember that sclerenchyma cells are typically dead and provide support, while parenchyma cells are living and involved in storage and metabolism.
		2. Misunderstanding lignification: Lignification is a key feature of sclerenchyma; ensure to remember that it refers to the thickening of cell walls with lignin.
	**Quick Tips**:
		1. To identify plant cell types, focus on their functions: support (sclerenchyma), flexibility (collenchyma), and storage (parenchyma).
		2. Remember that sclerenchyma cells are often found in areas requiring strong structural integrity, like stems and seed coats.
