The type of ribosomes is same in:

Options

A. 1)Cytoplasm of eukaryotic cells, their mitochondria and chloroplasts.
B. 2)cytoplasm of eukaryotic cells, their chloroplasts and microbodies.
C. 3)Prokaryotes, mitochondria and chloroplasts.
D. 4) Eukaryotic cytoplasm, mitochondria and endo plasmic reticulum.

Answer

To determine which option contains the same type of ribosomes, we need to analyze the ribosomal types found in the different cellular components mentioned in each option.

### Step-by-Step Solution:

1. **Understanding Ribosomes**:
- Ribosomes are the cellular structures responsible for protein synthesis. They can be found in both prokaryotic and eukaryotic cells.
- Ribosomes can be classified based on their sedimentation coefficient (S), which is a measure of their size. In eukaryotic cells, ribosomes are typically 80S, while in prokaryotic cells, they are 70S.

2. **Analyzing the Options**:
- **Option 1**: Cytoplasm of eukaryotic cells (80S), mitochondria (70S), and chloroplast (70S).
- These ribosomes are not the same. **(Incorrect)**
- **Option 2**: Cytoplasm of eukaryotic cells (80S), chloroplast (70S), and microbodies (70S).
- These ribosomes are also not the same. **(Incorrect)**
- **Option 3**: Prokaryotes (70S), mitochondria (70S), and chloroplast (70S).
- All three contain 70S ribosomes. **(Correct)**
- **Option 4**: Eukaryotic cytoplasm (80S), mitochondria (70S), and endoplasmic reticulum (80S).
- These ribosomes are not the same. **(Incorrect)**

3. **Conclusion**:
- The only option where the type of ribosomes is the same is **Option 3**, which includes prokaryotes, mitochondria, and chloroplasts, all of which contain 70S ribosomes.

### Final Answer:
**The type of ribosomes is the same in Option 3: Prokaryotes, mitochondria, and chloroplast.**
