Which cell organelle comprises of cis and trans faces ?

Options

A. Endoplasmic reticulum
B. Golgi body
C. Ribosomes
D. Mitochondria

Answer

To solve the question "Which cell organelle comprises of cis and trans faces?", we can follow these steps:

### Step 1: Understand the Question
The question is asking about a specific cell organelle that has structures referred to as "cis" and "trans" faces.

**Hint:** Look for organelles that have distinct sides or faces that serve different functions.

### Step 2: Review the Options
The options provided are:
1. Androplasmic reticulum
2. Golgi body
3. Ribosomes
4. Mitochondria

**Hint:** Consider the functions and structures of each organelle to determine if they have "cis" and "trans" faces.

### Step 3: Analyze Each Option
- **Androplasmic Reticulum:** This organelle is involved in protein and lipid synthesis. It does not have cis and trans faces.

- **Golgi Body:** The Golgi body, also known as the Golgi apparatus, consists of a series of flattened membrane-bound sacs called cisternae. It has two distinct sides: the cis face (receiving side) and the trans face (shipping side). This organelle is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

- **Ribosomes:** Ribosomes are the sites of protein synthesis and are not membrane-bound organelles. They do not have cis and trans faces.

- **Mitochondria:** Mitochondria are known as the powerhouse of the cell, responsible for ATP production. They do not have cis and trans faces.

**Hint:** Identify which organelle has a structure that includes distinct receiving and shipping sides.

### Step 4: Identify the Correct Answer
Based on the analysis, the Golgi body is the only organelle that has cis and trans faces. The cis face receives transport vesicles, while the trans face is where secretory vesicles are dispatched.

**Final Answer:** The correct option is **Golgi body**.

### Summary of Steps
1. Understand the question.
2. Review the options.
3. Analyze each organelle's structure and function.
4. Identify the correct answer based on the presence of cis and trans faces.
