Cytokinesis is inhibited if the following becomes non functional

Options

A. Phragmoplast
B. Ribosomes
C. Lysosomes
D. Dictyosomes

Answer

**Step-by-Step Solution:**

1. **Understanding Cytokinesis**: Cytokinesis is the final stage of cell division (mitosis) where the cytoplasm of a parental cell is divided into two daughter cells. It is crucial for the completion of cell division.

2. **Identifying Key Structures**: In the context of cytokinesis, certain cellular structures play a significant role. We need to identify which of these structures, if non-functional, would inhibit cytokinesis.

3. **Analyzing the Options**:
- **Option A: Phragmoplast**: This structure is involved in the formation of the cell plate during cytokinesis in plant cells. If it is non-functional, cytokinesis would be affected.
- **Option B: Ribosomes**: These are responsible for protein synthesis but do not directly influence the process of cytokinesis.
- **Option C: Lysosomes**: These are involved in digestion within the cell but are not directly related to the process of cytokinesis.
- **Option D: Dictuosomes**: These are part of the Golgi apparatus and are involved in the secretion and processing of proteins. If dictuosomes become non-functional, it can affect the formation of the cell plate and subsequently inhibit cytokinesis.

4. **Conclusion**: Based on the analysis, the structure that, if non-functional, would inhibit cytokinesis is the **dictuosomes**.

**Final Answer**: The answer is **Option D: Dictuosomes**.
