Which of the following is present in the prokaryotes?

Options

A. Nuclear envelope
B. Golgi apparatus
C. Mitochondria
D. Ribosomes

Answer

To determine which of the following is present in prokaryotes, we need to analyze the options provided and understand the characteristics of prokaryotic cells.

### Step-by-Step Solution:

1. **Understand Prokaryotic Cells**: Prokaryotic cells are characterized by the absence of a nuclear envelope and membrane-bound organelles. They are simpler and smaller compared to eukaryotic cells.

2. **Evaluate the Options**:
- **Option 1: Nuclear Envelope**: Prokaryotes do not have a nuclear envelope. This option is incorrect.
- **Option 2: Golgi Apparatus**: The Golgi apparatus is a membrane-bound organelle found only in eukaryotic cells. This option is incorrect.
- **Option 3: Mitochondria**: Mitochondria are also membrane-bound organelles and are present only in eukaryotic cells. This option is incorrect.
- **Option 4: Ribosomes**: Ribosomes are not membrane-bound and are present in both prokaryotic and eukaryotic cells. They are essential for protein synthesis. This option is correct.

3. **Conclusion**: The only structure from the options that is present in prokaryotes is ribosomes.

### Final Answer:
The cell organelle which is present in prokaryotes is **ribosomes**.
