Question

Which of the following statements regarding the cell wall of parenchyma cells is INCORRECT?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant cell wall structure and function, specifically in parenchyma cells.
	**Related Topics**: Plant tissues, cell biology, cellulose, lignin, plasmodesmata.
	**Prerequisites**: Basic understanding of plant cell structure.
## SOLUTION PATHWAY
**Given Information**:
	Multiple-choice question about parenchyma cell walls.
**Method & Steps**:
	1. Analyze each statement based on known characteristics of parenchyma cell walls.
	2. Identify the incorrect statement.
## OPTION ANALYSIS
[A] ✓: The cell wall of parenchyma cells is primarily composed of cellulose. 
Reasoning: This is a correct statement. Cellulose is the main structural component of parenchyma cell walls.
[B] ✓: The cell wall of parenchyma cells allows for flexibility and expansion.
Reasoning: This is a correct statement. Parenchyma cells are often involved in growth and storage, requiring flexible cell walls.
[C] ✓: The cell wall of parenchyma cells is connected to adjacent cells via plasmodesmata. 
Reasoning: This is a correct statement. Plasmodesmata are channels that connect adjacent plant cells, allowing for communication and transport.
[D] :x: The cell wall of parenchyma cells is heavily lignified.
Reasoning: This is the incorrect statement.  Lignin provides rigidity and is typically found in cells needing structural support, such as sclerenchyma cells. Parenchyma cell walls are typically thin and flexible, lacking significant lignification.  This lack of lignification allows for functions like storage and photosynthesis.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing parenchyma cells with sclerenchyma cells: Sclerenchyma cells have heavily lignified cell walls, unlike parenchyma cells.
			How to avoid: Remember the functions of each cell type. Parenchyma cells are involved in storage and metabolism, while sclerenchyma cells provide structural support.
		2. Overgeneralizing cell wall composition: Not all plant cell walls are the same.
			How to avoid: Learn the specific characteristics of different plant cell types and their cell walls.
	**Quick Tips**:
		1. Parenchyma = Photosynthesis, storage, flexibility.
		2. Lignin = Rigidity, strength (think wood).
