Most resistance biological material is
Or
An organic substance that can withstand enviornmental extremes and cannot be degraded by any enzyme is

Options

A. liginin
B. cellulose
C. cuticel
D. sporopollenin

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a biological material that is resistant to environmental extremes and cannot be degraded by any enzyme.

2. **Analyzing the Options**:
- **Option 1: Lignin**: Lignin is a complex organic polymer found in the cell walls of many plants, providing rigidity and resistance to decay. However, it is not impervious to all substances and does not fit the criteria of being completely indestructible by enzymes.
- **Option 2: Cellulose**: Cellulose is a polysaccharide that forms the primary structural component of plant cell walls. It can be degraded by cellulase enzymes, making it an incorrect option.
- **Option 3: Cuticle Layer**: The cuticle is a waxy layer found on the surface of leaves that helps prevent water loss. While it provides some resistance to environmental factors, it is not a biological material that fits the description of being indestructible by enzymes.
- **Option 4: Sporopollenin**: Sporopollenin is a biopolymer found in the outer layer of pollen grains. It is known for its incredible resistance to degradation by enzymes and can withstand extreme environmental conditions, including high temperatures and strong acids or bases.

3. **Conclusion**: After analyzing all the options, sporopollenin is the only substance that meets the criteria of being a resistant biological material that cannot be degraded by any enzyme and can withstand environmental extremes.

4. **Final Answer**: The correct answer is **sporopollenin**.
