### Identification of Unbounded Structures

1. **Understanding Membrane-Bound Organelles**
- Membrane-bound organelles are structures within a cell that are enclosed by lipid membranes. Examples include the endoplasmic reticulum, mitochondria, Golgi body, and nucleus.

2. **Analyzing the Options**
- **Endoplasmic Reticulum**: Membrane-bound organelle involved in protein and lipid synthesis.
- **Mitochondria**: Membrane-bound organelle known as the powerhouse of the cell, involved in energy production.
- **Golgi Body**: Membrane-bound organelle that modifies, sorts, and packages proteins.
- **Ribosomes**: Non-membrane-bound structures responsible for protein synthesis.
- **Nucleus**: Membrane-bound organelle that contains genetic material.

### Final Answer
Ribosomes are not bounded by membranes.
