Answer

To answer the question about how many components are present in a fully developed Golgi apparatus, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**:
- The Golgi apparatus is a crucial organelle in eukaryotic cells, responsible for modifying, sorting, and packaging proteins and lipids.

2. **Components of the Golgi Apparatus**:
- The Golgi apparatus consists of several compartments, primarily organized into two main networks:
- **Cis-Golgi Network (CGN)**: This is the receiving side of the Golgi apparatus.
- **Trans-Golgi Network (TGN)**: This is the shipping side of the Golgi apparatus.

3. **Identifying the Four Main Components**:
- The fully developed Golgi apparatus has four key components:
1. **Cisternae**: These are flat, stacked membrane-bound structures that are arranged in parallel. Each cisterna has two phases: a proximal (forming) phase and a distal (maturing) phase.
2. **Vacuoles**: Known as Golgian vacuoles, these are round sacs located at the distal end of the cisternae, which serve as storage or transport vesicles.
3. **Vesicles**: These are small, membrane-bound droplets that are found at the periphery of the cisternae. They can be classified into two types: smooth vesicles and coated vesicles.
4. **Tubules**: These are thin, tubular structures that form a network, connecting different parts of the Golgi apparatus.

4. **Conclusion**:
- Based on the above information, we conclude that a fully developed Golgi apparatus consists of **four components**: cisternae, vacuoles, vesicles, and tubules.

### Final Answer:
The fully developed Golgi apparatus has **four components**.
