In angiosperms various stages of reductional division can best be studied in

Options

A. young anthers
B. mature anthers
C. young ovules
D. endosperm cells

Explanation

To answer the question "In angiosperms, various stages of reductional division can best be studied in," we will analyze each option provided and determine where meiosis occurs in angiosperms.

### Step-by-Step Solution:

1. **Understanding Reductional Division**:
- Reductional division refers to meiosis, which is the process that reduces the chromosome number by half and is essential for sexual reproduction in flowering plants (angiosperms).

2. **Identifying the Location of Meiosis**:
- Meiosis occurs in the reproductive structures of angiosperms, specifically in the anthers (which produce pollen) and ovules (which produce eggs).

3. **Evaluating the Options**:
- **Option A: Young Anthers**:
- Young anthers contain microspore mother cells that are undergoing meiosis. This is where the various stages of reductional division can be observed.
- **Option B: Mature Anthers**:
- In mature anthers, meiosis has already been completed, and therefore, the stages of reductional division cannot be studied here.
- **Option C: Young Ovules**:
- Young ovules also undergo meiosis, but they do not provide a clear comparison of the various stages as effectively as young anthers.
- **Option D: Androsperm Cells**:
- Androsperm cells are formed after fertilization and do not undergo meiosis, so they cannot be used to study the stages of reductional division.

4. **Conclusion**:
- The best option for studying the various stages of reductional division in angiosperms is **Option A: Young Anthers**.

### Final Answer:
In angiosperms, various stages of reductional division can best be studied in **young anthers**.
