which of the following statement is incorrect W.r.t. Golgi apparatus?

Options

A. It is non- membrane bound organelle
B. It is composed of flattened sacs called cisternae
C. Cisternae resemble with SER
D. Gogli apparatus has two faces- cis and trans

Answer

To determine which statement is incorrect with respect to the Golgi apparatus, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**:
- The Golgi apparatus is an essential organelle in eukaryotic cells, primarily involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Analyzing Each Statement**:
- **Option 1**: "It is non-membrane bound."
- This statement is incorrect. The Golgi apparatus is composed of membranes and is indeed a membrane-bound organelle.

- **Option 2**: "It is composed of flattened sacs."
- This statement is correct. The Golgi apparatus consists of flattened membrane-bound sacs called cisternae.

- **Option 3**: "Cisternae resemble a smooth endoplasmic reticulum."
- This statement is incorrect. Cisternae of the Golgi apparatus resemble the rough endoplasmic reticulum, not the smooth endoplasmic reticulum, because they are involved in processing and packaging proteins.

- **Option 4**: "Golgi apparatus has two phases: cis and trans."
- This statement is correct. The Golgi apparatus has a cis phase (the receiving side) and a trans phase (the shipping side), which are crucial for its function.

3. **Identifying Incorrect Statements**:
- From the analysis, we find that Options 1 and 3 are incorrect regarding the Golgi apparatus.

### Conclusion:
The incorrect statements with respect to the Golgi apparatus are:
- Option 1: "It is non-membrane bound."
- Option 3: "Cisternae resemble a smooth endoplasmic reticulum."
