### Analysis of Options

1. **RBCs (Red Blood Cells)**: These are whole cells that contain hemoglobin and are involved in transporting oxygen and carbon dioxide.

2. **WBCs (White Blood Cells)**: These are also whole cells responsible for immune responses in the body.

3. **Platelets**: These are cell fragments derived from megakaryocytes in the bone marrow and are involved in blood clotting.

4. **Albumins**: These are proteins found in blood plasma, not cells or cell fragments.

5. **Globulins**: Similar to albumins, these are also proteins in blood plasma, not cells or fragments.

### Final Answer
**Platelets** are the only option that are actually cell fragments and not whole cells.
