Within the cells ribosomes are found in

Options

A. chloroplast, mitochondria
B. rough E.R. microbodies
C. chromoplast,golgi complex
D. mitochondria , and lysosomes

Answer

**Step-by-Step Solution:**

1. **Understanding Ribosomes:**
- Ribosomes are granular structures made up of ribonucleic acid (RNA) and proteins. They are essential for protein synthesis in the cell and are often referred to as the "protein factories."

2. **Location of Ribosomes:**
- Ribosomes can be found in both prokaryotic and eukaryotic cells. In eukaryotic cells, ribosomes are located in various organelles.

3. **Identifying Organelles with Ribosomes:**
- In eukaryotic cells, ribosomes are present in:
- **Mitochondria:** These are double membrane-bound organelles that have their own DNA and ribosomes.
- **Chloroplasts:** Similar to mitochondria, chloroplasts are also double membrane-bound and contain their own DNA and ribosomes.
- **Rough Endoplasmic Reticulum (RER):** Ribosomes are attached to the surface of the RER, giving it a "rough" appearance.

4. **Eliminating Incorrect Options:**
- Microbodies, Chromoplasts, Golgi Complex, and Lysosomes do not contain ribosomes.
- Microbodies are vesicles containing enzymes, Chromoplasts are involved in pigment synthesis, Golgi Complex is involved in modifying and packaging proteins, and Lysosomes contain hydrolytic enzymes.

5. **Conclusion:**
- The organelles where ribosomes are present include mitochondria, chloroplasts, and the rough endoplasmic reticulum. Therefore, the correct answer to the question is that ribosomes are found in mitochondria and chloroplasts.

**Final Answer:**
Ribosomes are found in mitochondria and chloroplasts.
