The golgi components are bound by :–

Options

A. Single unit membrane
B. Double unit membrane
C. Cisternae by single, tubules and vacuole by double
D. Cristae by single, tubules and vacuole by double

Answer

To answer the question "The Golgi components are bound by:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Golgi Apparatus**: The Golgi apparatus, also known as the Golgi complex, is a vital organelle in eukaryotic cells. It is involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Identify the Membrane Type**: The question asks about the type of membrane that bounds the Golgi components. The Golgi apparatus is made up of a series of flattened, membrane-bound sacs called cisternae.

3. **Determine the Correct Option**: The options provided include:
- (1) Single unit membrane
- (2) Double unit membrane
- (3) Single tibials
- (4) Vacuoles by double

The correct answer is option (1) Single unit membrane. The Golgi apparatus is bound by a single membrane, which distinguishes it from organelles like mitochondria, which are bound by a double membrane.

4. **Explain Why Other Options Are Incorrect**:
- Option (2) Double unit membrane is incorrect because, as mentioned, the Golgi apparatus has a single membrane.
- Options (3) and (4) do not accurately describe the Golgi apparatus or its membrane structure.

5. **Conclusion**: Therefore, the Golgi components are bound by a single unit membrane, making option (1) the correct answer.

### Final Answer:
The Golgi components are bound by: **Single unit membrane** (Option 1).
