Which of these cell organelles helps in the transport of proteins and other substances to different parts of the cell

Options

A. Mitochondria
B. Centrioles
C. Lysosomes
D. Endoplasmic reticulum

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which cell organelle is responsible for transporting proteins and other substances within the cell.

2. **Identifying the Options**: The options provided are:
- A) Mitochondria
- B) Centrioles
- C) Lysosomes
- D) Endoplasmic Reticulum

3. **Analyzing Each Option**:
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria are primarily involved in energy production, not transport.
- **Centrioles**: These are involved in cell division and the organization of the mitotic spindle, not in transport.
- **Lysosomes**: These organelles are responsible for breaking down waste materials and cellular debris, not for transport.
- **Endoplasmic Reticulum (ER)**: The ER is a network of membranes involved in the synthesis and transport of proteins and other substances within the cell.

4. **Conclusion**: Based on the analysis, the organelle that helps in the transport of proteins and other substances to different parts of the cell is the **Endoplasmic Reticulum**.

5. **Final Answer**: The correct answer is **D) Endoplasmic Reticulum**.
