Sculpturing of exine of pollen is important in

Options

A. mitotic studies
B. physiologicl studies
C. taxonomic studies
D. medicinal studies

Answer

**Step-by-Step Solution:**

1. **Understanding the Exine of Pollen:**
- The exine is the outer layer of the pollen grain, which is known for its durability and protective qualities. It is composed of a tough substance called sporopollenin, which is resistant to decay and environmental factors.

2. **Importance of Sculpturing:**
- The sculpturing of the exine refers to the various patterns and textures that can be found on the surface of pollen grains. These patterns can vary significantly between different species of plants.

3. **Role of Exine in Taxonomy:**
- The sculpturing of the exine is particularly important in taxonomic studies. Taxonomy is the science of classification, and the unique characteristics of pollen exine can help in identifying and classifying different plant species.

4. **Exclusion of Other Studies:**
- While mitotic studies (related to cell division) and physiological studies (related to the functions of living organisms) do not directly involve the characteristics of pollen exine, taxonomic studies utilize these characteristics for classification purposes.
- Medicinal studies also do not relate to the sculpturing of exine.

5. **Conclusion:**
- Therefore, the sculpturing of the exine of pollen is important primarily in taxonomic studies, as it aids in the identification and classification of plant species.

**Final Answer:**
The sculpturing of the exine of pollen is important in taxonomic studies.
