Question

Which component of pollen grains allows them to resist decay and become fossilized?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A. Sporopollenin
## CONCEPT FRAMEWORK
 **Primary Concept**: Pollen preservation and its chemical composition
 **Related Topics**: Palynology, plant anatomy, taphonomy
 **Prerequisites**: Basic knowledge of plant cell walls and fossilization.
## SOLUTION PATHWAY
**Given Information**:
  The question focuses on the component enabling pollen resistance to decay and fossilization.
  Options: Sporopollenin, Callose, Suberin, Lignin
**Method & Steps**:
 1. Identify the key property needed for fossilization: resistance to degradation.
  Reasoning:  Pollen must withstand decomposition to become fossilized.
  Formula/Rule: None directly applicable.
 2. Evaluate the decay resistance of each component:
  Working: Sporopollenin is known for its exceptional resistance to chemical and biological degradation, unlike the other options.
  Key Point: Sporopollenin's robust chemical structure is crucial for long-term preservation.
 3. Determine the component responsible for pollen fossilization:
  Result: Sporopollenin is the component that allows pollen grains to resist decay and become fossilized.
  Verification: This is a well-established fact in palynology.
 ## OPTION ANALYSIS
A ✓: Sporopollenin is the primary component providing the resistance to decay.
B :x: Callose is a temporary component of plant cell walls.
C :x: Suberin is found in corky tissues, not primarily in pollen.
D :x: Lignin is found in woody tissues and is less resistant to decay than sporopollenin.
 ## LEARNING AIDS
 **Common Mistakes**: Confusing sporopollenin with other plant cell wall components.
 **Quick Tips**: Remember sporopollenin's role in protecting pollen from degradation.
