Cytoplasmic structures involved in cell division are

Options

A. Mitochondria
B. Ribosomes
C. Lysosomes
D. Centrioles

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for cytoplasmic structures that are involved in cell division. This implies that we need to identify organelles or structures within the cytoplasm that play a role during the process of cell division.

2. **Reviewing the Options**:
- **Option 1: Mitochondria** - These organelles are primarily involved in energy production (ATP synthesis) and do not play a direct role in cell division.
- **Option 2: Ribosomes** - Ribosomes are responsible for protein synthesis. While proteins are essential for many cellular processes, ribosomes themselves do not directly participate in cell division.
- **Option 3: Lysosomes** - Lysosomes are involved in cellular digestion and waste processing. They contain hydrolytic enzymes but are not directly involved in the mechanics of cell division.
- **Option 4: Centrioles** - Centrioles are critical structures in cell division. They help organize the spindle fibers that separate chromosomes during the metaphase and anaphase stages of mitosis.

3. **Identifying the Correct Answer**: Based on the functions of each option, centrioles are the only cytoplasmic structures that are directly involved in the process of cell division. They play a key role in forming the spindle apparatus that is essential for chromosome separation.

4. **Conclusion**: Therefore, the correct answer to the question is **Option 4: Centrioles**.
