In palynology, we study which of the following?

Options

A. Sperms
B. Spores
C. Male gametophytes and spores
D. Pollen grains and mega gametophytes

Answer

**Step-by-Step Solution:**

1. **Understanding Palynology**:
- Palynology is defined as the scientific study of pollen grains and spores. It is a branch of botany that focuses on the analysis of pollen and spores from various plants.

2. **Identifying Key Terms**:
- The question provides several terms: sperm, spores, male gametophyte, and pollen grain. We need to identify which of these is primarily studied in palynology.

3. **Analyzing the Options**:
- **Sperm**: This refers to the male reproductive cells but is not specifically studied in palynology.
- **Spores**: These are reproductive units in plants like ferns and fungi but are not the main focus of palynology.
- **Male Gametophyte**: This is the structure that produces pollen in flowering plants (angiosperms) and is a key focus in palynology.
- **Pollen Grain and Male Gametophyte**: Pollen grains are the male gametophytes in seed plants, which are indeed studied in palynology.

4. **Conclusion**:
- The correct answer is that in palynology, we study pollen grains, which are the male gametophytes of angiosperms and gymnosperms.

5. **Final Answer**:
- The correct option is "pollen grain and male gametophyte".
