Which of the following statements is correct

Options

A. Sporopollenin can be degraded by enzymes
B. Sporopollenin in made up to inorganic materials
C. Sporopollenin can withstand high temperature as well as strong acids and alkalis
D. Sporopollenin can withstand high temperature but not strong acids

Answer

To solve the question, we need to analyze each of the statements regarding sporopollenin, the material that makes up the outer layer of pollen grains.

1. **Understanding Sporopollenin**:
- Sporopollenin is a highly resistant organic compound found in the exine (outer layer) of pollen grains. It is known for its durability and resistance to degradation.

2. **Evaluating Each Statement**:
- **Statement 1**: "Sporopollenin can be degraded by enzymes."
- This statement is incorrect. Sporopollenin is resistant to enzymatic degradation, and there are no known enzymes that can break it down.

- **Statement 2**: "Sporopollenin is made up of inorganic materials."
- This statement is also incorrect. Sporopollenin is an organic compound, not inorganic.

- **Statement 3**: "Sporopollenin can withstand high temperature as well as strong acids and alkalis."
- This statement is correct. Sporopollenin is known for its ability to withstand extreme conditions, including high temperatures and strong acids and bases.

- **Statement 4**: "Sporopollenin can withstand high temperature but not strong acids."
- This statement is incorrect. As mentioned, sporopollenin can withstand both high temperatures and strong acids.

3. **Conclusion**:
- The only correct statement among the options provided is Statement 3: "Sporopollenin can withstand high temperature as well as strong acids and alkalis."

### Final Answer:
The correct statement is: **Sporopollenin can withstand high temperature as well as strong acids and alkalis.**
