Common semi autonomous cell organelles found in all eukaryotic cells are

Options

A. Plastids
B. Mitochondria
C. Nucleus
D. 1 & 2

Answer

To answer the question about common semi-autonomous cell organelles found in all eukaryotic cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Semi-Autonomous Organelles**:
- Semi-autonomous organelles are those that have their own DNA and can synthesize some of their own proteins. This means they can perform specific functions independently to some extent.

2. **Identifying the Options**:
- The options provided are:
- Option 1: Plastids
- Option 2: Mitochondria
- Option 3: Nucleus
- Option 4: Both Plastids and Mitochondria

3. **Analyzing Each Option**:
- **Plastids**: These organelles, such as chloroplasts, contain their own DNA and are involved in functions like photosynthesis. They are considered semi-autonomous.
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria also have their own DNA and are responsible for energy production. They are also classified as semi-autonomous.
- **Nucleus**: While the nucleus contains DNA, it is not considered a semi-autonomous organelle because it does not produce its own proteins independently like plastids and mitochondria do.

4. **Conclusion**:
- Based on the analysis, both plastids and mitochondria are semi-autonomous organelles found in all eukaryotic cells. Therefore, the correct answer is option 4: Both Plastids and Mitochondria.

### Final Answer:
The common semi-autonomous cell organelles found in all eukaryotic cells are Plastids and Mitochondria (Option 4).
