Golgi apparatus develops from

Options

A. Endoplasmic reticulum
B. Lysosome
C. Mitochondria
D. Cell membrane

Explanation

**Step-by-Step Solution:**

1. **Identify the Origin of Golgi Apparatus:**
The Golgi apparatus develops from the endoplasmic reticulum (ER). This is a crucial point as it establishes the relationship between these two organelles.

2. **Understand the Structure of Golgi Apparatus:**
The Golgi apparatus is a stacked structure found in various cells, primarily eukaryotic cells. It consists of flattened membranous sacs known as cisternae.

3. **Recognize the Functions of Golgi Apparatus:**
The Golgi apparatus has several major functions, including:
- Modifying proteins and lipids synthesized in the ER.
- Packaging these molecules into vesicles for transport to their target locations.

4. **Explore the Theories of Golgi Apparatus Development:**
There are two main theories regarding the development of the Golgi apparatus:
- **First Theory:** The Golgi apparatus is present in the first cell and gradually adds proteins, fusing to create additional stacks.
- **Second Theory:** The Golgi apparatus consists of cis-Golgi and trans-Golgi, where the cis-type is present in the first cell and the trans-type is present in a subsequent cell.

5. **Conclude the Development Process:**
The Golgi apparatus develops through the modification and packaging of materials that originate from the endoplasmic reticulum, leading to its formation and functionality in the cell.
