Identify the cell organelles that are responsible for intercellular transport system.

Options

A. Mitochondria
B. Ribosome
C. Endoplasmic reticulum
D. Golgi complex

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the identification of cell organelles responsible for the intercellular transport system. Intercellular transport refers to the movement of materials within a cell.

2. **Reviewing the Options**: The options given are:
- Mitochondria
- Ribosome
- Endoplasmic Reticulum
- Golgi Complex

3. **Analyzing Each Option**:
- **Mitochondria**: These are known as the powerhouses of the cell, primarily involved in energy production (ATP synthesis) but not directly involved in transport.
- **Ribosome**: Ribosomes are responsible for protein synthesis, not transport.
- **Endoplasmic Reticulum (ER)**: The ER is a network of membranes involved in the synthesis and transport of proteins and lipids. It is divided into two types: Rough ER (which has ribosomes and synthesizes proteins) and Smooth ER (which synthesizes lipids).
- **Golgi Complex**: This organelle modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles, but it is not primarily responsible for transport within the cell.

4. **Identifying the Correct Answer**: Based on the analysis, the Endoplasmic Reticulum is the organelle responsible for the intercellular transport system due to its extensive network that facilitates the movement of materials within the cell.

5. **Conclusion**: The correct answer is the **Endoplasmic Reticulum**.
