Amembrane bound systems which are present freely in the cytoplasm

Options

A. Ribosomes
B. Inclusion bodies
C. Residual bodies
D. Baker's bodies

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a membrane-bound system that is found freely in the cytoplasm of a cell.

2. **Identifying Membrane-Bound Organelles**: In eukaryotic cells, there are several membrane-bound organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. However, we need to focus on those that are present freely in the cytoplasm.

3. **Recognizing Ribosomes**: Ribosomes are unique because they are not surrounded by a membrane, but they are often referred to in the context of membrane-bound systems due to their association with the endoplasmic reticulum (rough ER). However, ribosomes can exist freely in the cytoplasm as well.

4. **Conclusion**: The answer to the question is ribosomes. They are not membrane-bound in the traditional sense, but they are essential for protein synthesis and can be found freely floating in the cytoplasm.

**Final Answer**: Ribosomes are the membrane-bound systems that are present freely in the cytoplasm.
