A cell organelle 'x' is divided into two types on the basis of a cell organelle 'y' , that helps in the protein synthesis. Identify 'x' and 'y' respectively

Options

A. Golgi complex and ribosome
B. ER and mitochondria
C. ER and ribosome
D. Lysosomes and ER

Answer

To solve the question, we need to identify the cell organelle 'x' that is divided into two types based on another organelle 'y' that helps in protein synthesis. Let's break down the solution step by step.

### Step-by-Step Solution:

1. **Identify the organelle involved in protein synthesis (Y)**:
- The organelle that is primarily responsible for protein synthesis in cells is the ribosome. Ribosomes can be found in both prokaryotic and eukaryotic cells and are essential for translating mRNA into proteins.

**Hint**: Think about which organelle is known for assembling amino acids into proteins.

2. **Determine the organelle that is divided into two types (X)**:
- The organelle that is divided into two types based on the presence of ribosomes is the endoplasmic reticulum (ER). The ER can be categorized into two types:
- Rough Endoplasmic Reticulum (RER): This type has ribosomes attached to its surface, giving it a "rough" appearance and is involved in protein synthesis.
- Smooth Endoplasmic Reticulum (SER): This type lacks ribosomes and is primarily involved in lipid synthesis.

**Hint**: Consider which organelle has two forms based on the presence of ribosomes.

3. **Conclusion**:
- Based on the analysis, we can conclude that:
- 'X' is the Endoplasmic Reticulum (ER).
- 'Y' is the Ribosomes.

### Final Answer:
- **X**: Endoplasmic Reticulum (ER)
- **Y**: Ribosomes
