D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Cell Types and Tissue Structure
 **Related Topics**: Fruit anatomy, sclereids, cell wall composition
 **Prerequisites**: Basic understanding of plant cell types and their functions.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the cause of the gritty texture in pear fruit.
**Method & Steps**:
1. Identify cell types contributing to texture in fruits.
  Reasoning:  Different plant cells have different properties that affect texture.  Stone cells (sclereids) are known for their hard, gritty texture due to their thick, lignified secondary cell walls.
  Formula/Rule: None directly applicable.
2. Analyze the characteristics of each option.
  Working: 
        * **Stone cells (sclereids):** These cells have thick, lignified secondary cell walls, making them hard and gritty. This is the primary reason for the gritty texture in pears.
        * **Collenchyma cells:** These cells have unevenly thickened primary cell walls and provide support to young plant organs. They are not typically associated with a gritty texture.
        * **Parenchyma cells:** These are thin-walled cells that make up the bulk of plant tissue. They are soft and do not contribute to a gritty texture.
        * **Xylem vessels:** These are specialized cells involved in water transport in plants. They do not contribute to the gritty texture of pears.
 3. Determine the correct cell type responsible for the gritty texture.
  Result: Stone cells (sclereids) are responsible for the gritty texture of pear fruit.
  Verification: The characteristics of sclereids align perfectly with the described gritty texture.
 ## OPTION ANALYSIS
A ✓: Stone cells (sclereids) are hard and gritty due to their thick, lignified secondary cell walls. This correctly identifies the cause of the gritty texture in pears.
B :x: Collenchyma cells provide support but are not known for a gritty texture.
C :x: Parenchyma cells are soft and do not contribute to grittiness.
D :x: Xylem vessels are involved in water transport and do not cause grittiness.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing collenchyma cells with sclereids: Collenchyma cells are supportive but not as hard as sclereids.
   [How to avoid]: Understand the distinct cell wall structures and functions of each cell type.
  2.Overlooking the significance of lignification: Lignin is a key component of sclereid cell walls that contributes to their hardness.
   [How to avoid]: Remember that lignified cell walls are characteristic of hard tissues in plants.
 **Quick Tips**:
  1.Remember that grittiness in fruits is often associated with the presence of sclereids.
  2.Associate lignified cell walls with hardness and strength in plant tissues.
