Which of the following do prokaryotes possess ?
(a) Mitochondria
(b) Golgi body
(c) Meiotic mechanisms
(d) Ribosomes

Options

A. Mitochondria
B. Golgi body
C. Meiotic mechanisms
D. Ribosomes

Explanation

To solve the question "Which of the following do prokaryotes possess?" we will analyze each option provided:

1. **Understanding Prokaryotes**: Prokaryotes are unicellular organisms that lack a true nucleus and membrane-bound organelles. Their genetic material is not enclosed within a nuclear membrane but is instead found in a region called the nucleoid.

2. **Analyzing Each Option**:
- **(a) Mitochondria**: Prokaryotes do not possess mitochondria. Mitochondria are membrane-bound organelles responsible for energy production in eukaryotic cells. Since prokaryotes lack membrane-bound organelles, this option is incorrect.

- **(b) Golgi body**: Similar to mitochondria, prokaryotes do not have a Golgi body. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids in eukaryotic cells. Therefore, this option is also incorrect.

- **(c) Meiotic mechanisms**: Prokaryotes do not undergo meiosis. Meiosis is a type of cell division that produces gametes and is characteristic of eukaryotic organisms. Prokaryotes typically reproduce asexually through binary fission, making this option incorrect as well.

- **(d) Ribosomes**: Prokaryotes do possess ribosomes, which are essential for protein synthesis. Prokaryotic ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S), but they are present and functional in prokaryotic cells. Thus, this option is correct.

3. **Conclusion**: The only structure that prokaryotes possess from the options given is **(d) Ribosomes**.

**Final Answer**: (d) Ribosomes
