The correct Answer is:
### Step-by-Step Solution 1. **Identify the Organelle**: The Golgi body, also known as the Golgi apparatus, is a cell organelle found in eukaryotic cells. It is absent in prokaryotic cells. 2. **Structure of Golgi Body**: The Golgi body consists of a series of flattened, disc-shaped sacs called cisternae. These structures are densely stained and are located near the nucleus of the cell. 3. **Phases of Golgi Body**: The Golgi body has two main phases: - **Cis Phase**: This is the receiving phase where incoming transport vesicles arrive with proteins and lipids from the endoplasmic reticulum (ER). - **Trans Phase**: This is the shipping phase where modified proteins and lipids are packaged into secretory vesicles for transport to their destinations. 4. **Functions of Golgi Body**: - **Packaging**: The Golgi body is primarily responsible for the packaging of proteins and lipids. - **Modification**: Proteins synthesized in the endoplasmic reticulum are modified in the Golgi body. - **Secretion**: The main function of the Golgi body is secretion. The secretory vesicles formed in the trans phase release their contents outside the cell. 5. **Clarification on Other Functions**: While the question mentions respiration, excretion, and degradation, these are not the primary functions of the Golgi body. Its main role is secretion. 6. **Conclusion**: The Golgi body is mainly concerned with secretion, packaging, and modification of proteins and lipids.
