1. **Understanding the Question**: The question asks who discovered the cell wall. This requires knowledge of historical figures in cell biology.

2. **Identifying Key Figures**: The video mentions several scientists: Robert Hooke, Robert Brown, Marcelo Malpighi, and Nagelli. We need to determine which of these is associated with the discovery of the cell wall.

3. **Analyzing Each Option**:
- **Robert Brown**: Known for discovering the nucleus of the cell, not the cell wall.
- **Marcelo Malpighi**: Recognized for his work on red blood cells, not related to the cell wall.
- **Robert Hooke**: In 1665, he observed cork under a microscope and described its structure, coining the term "cellula," which later became "cells." His observations included the cell wall.
