All structural details of cell were revealed through the following instrument

Options

A. Light microscope
B. Ultra centrifuge
C. Electron microscope
D. Phase contrast microscope

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which instrument has revealed all structural details of a cell. This indicates that we need to identify a specific type of microscope that has the capability to visualize cellular structures in detail.

2. **Reviewing Microscopes**: There are various types of microscopes, including light microscopes, scanning electron microscopes (SEM), and transmission electron microscopes (TEM). Each type has different capabilities in terms of magnification and resolution.

3. **Identifying the Key Instrument**: The electron microscope, particularly the transmission electron microscope (TEM), is known for its ability to provide high-resolution images of the internal structures of cells. It uses electron beams instead of light to achieve much higher magnification and resolution.

4. **Conclusion**: Based on the information gathered, the instrument that has revealed all structural details of a cell is the **electron microscope**.

**Final Answer**: The electron microscope.
