The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Pollen Structure**: Pollen grains consist of three main parts: the central cytoplasmic part, the inner layer (entire), and the outer layer (exine). The exine is the outermost and most durable layer. 2. **Composition of Exine**: The exine is primarily made of sporopollenin, which is highly resistant to degradation from heat, acids, and bases. This durability allows the exine to preserve the general form of the pollen grain over time. 3. **Importance of Exine Sculpturing**: The sculpturing of the exine, which includes its symmetrical structure and surface patterns, is crucial for identifying and classifying different types of pollen grains. 4. **Taxonomic Relevance**: The characteristics of the exine, such as its sculpturing, size, and the number of apertures (which are openings through which pollen tubes grow), serve as important taxonomic tools. This means that scientists can use these features to classify and identify plant species. 5. **Conclusion**: Based on the information about the role of exine sculpturing in identifying and classifying pollen grains, it is clear that the sculpturing of exine is important in taxonomic studies. **Final Answer**: Sculpturing of exine of pollen is important in taxonomic studies. ---
