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 regarding the correct statement about Sporopolynin, we will analyze each statement one by one based on the information provided.

### Step-by-Step Solution:

1. **Understanding Sporopolynin**:
- Sporopolynin is a compound that forms the outer wall of pollen grains, known as the exine.
- It is characterized as one of the hardest compounds found in nature.

**Hint**: Remember that Sporopolynin is crucial for the protection of pollen grains.

2. **Composition of Sporopolynin**:
- It is primarily made up of organic materials, specifically fats and phenolic compounds.
- This composition contributes to its durability.

**Hint**: Focus on the organic nature of Sporopolynin's composition.

3. **Resistance Properties**:
- Sporopolynin is known for its resistance to both chemical and physical damage.
- This includes resistance to enzymes, high temperatures, strong acids, and alkalis.

**Hint**: Consider the implications of its resistance when evaluating the statements.

4. **Evaluating the Statements**:
- **Statement 1**: "Sporopolynin can be degraded by enzymes."
- This is incorrect because Sporopolynin is resistant to enzymatic degradation.

- **Statement 2**: "Sporopolynin is made up of inorganic materials."
