The non-functioning of this cell organelle inhibits cytokinesis

Options

A. Ribosomes
B. Mitochondria
C. Golgi complex
D. chloroplast

Answer

**Step-by-Step Solution:**

1. **Understanding Cytokinesis**: Cytokinesis is the process during cell division where the cytoplasm of a parental cell is divided into two daughter cells. This process is crucial for the completion of cell division.

2. **Identifying the Organelle**: The question asks which cell organelle, when non-functioning, inhibits cytokinesis. We need to analyze the options provided.

3. **Evaluating Options**:
- **Option 1: Ribosome**: Ribosomes are responsible for protein synthesis. They do not play a direct role in cytokinesis. Therefore, this option is incorrect.

- **Option 2: Mitochondria**: Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration. They do not directly influence the process of cytokinesis. Thus, this option is also incorrect.

- **Option 3: Golgi Complex**: The Golgi complex is involved in modifying, sorting, and packaging proteins and lipids. In plant cells, during cytokinesis, vesicles from the Golgi apparatus gather at the center of the cell to form the cell plate, which is essential for dividing the cell. If the Golgi complex is non-functioning, the formation of the cell plate will be inhibited, leading to a failure in cytokinesis. Hence, this option is correct.

- **Option 4: Chloroplast**: Chloroplasts are involved in photosynthesis and do not have a role in cytokinesis. Therefore, this option is incorrect.

4. **Conclusion**: The correct answer is the Golgi complex, as its non-functioning directly inhibits cytokinesis in plant cells.

**Final Answer**: The non-functioning of the Golgi complex inhibits cytokinesis.
