Question

Which of the following complex tissues provides mechanical strength to the plant, especially in young dicotyledonous stems?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Tissues and their Functions
 **Related Topics**: Dicotyledonous stems, Mechanical Support in Plants, Cell Types in Plants
 **Prerequisites**: Basic understanding of plant anatomy and tissue types.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the complex tissue providing mechanical strength, specifically in young dicotyledonous stems.
  **Important conditions**: Young dicotyledonous stems are specified.
**Method & Steps**:
 1. Analyze the function of each tissue type.
  Reasoning: We need to identify the tissue responsible for providing mechanical support.
  Formula/Rule: N/A
 2. Consider the characteristics of young dicotyledonous stems.
  Working: Young stems are still growing and require flexibility along with strength.  Different tissues offer different types of support.
  Key Point:  Sclerenchyma provides rigidity but is less flexible than collenchyma.
 3. Identify the tissue best suited for the described function.
  Result: Collenchyma provides flexible support to young, growing stems, while sclerenchyma provides more rigid support to mature stems and other plant parts. Parenchyma is a packing tissue and xylem is primarily involved in water transport.
  Verification: Collenchyma's cell walls are unevenly thickened, providing flexibility and strength, which is ideal for young, growing stems of dicots.
 ## OPTION ANALYSIS
A :x: Parenchyma is a ground tissue involved in storage, photosynthesis, and secretion, not primarily mechanical support.
B :x: Sclerenchyma provides strong support but is rigid and less suited for young, growing stems. It's more common in mature parts.
C :x: Xylem is primarily involved in water transport, though it can contribute to structural support in mature plants.
D ✓: Collenchyma cells have unevenly thickened cell walls, providing flexibility and support, making them ideal for young, growing dicotyledonous stems.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing collenchyma and sclerenchyma: Remember that collenchyma provides flexible support, while sclerenchyma provides rigid support.
  2.Overlooking the 'young dicotyledonous stems' specification:  This narrows down the choices significantly.
 **Quick Tips**:
  1.Think of collenchyma as providing 'flexible strength' in young stems.
  2.Associate sclerenchyma with 'rigid strength' in mature plant parts.
