The cells discovered in thin sections of cork by Robert Hooke were actually

Options

A. Cellulose
B. Living cell
C. Cell coat
D. Cell waII

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: Robert Hooke is known for his discovery of cells in cork. He observed thin sections of cork under a microscope and described the structures he saw as "cells."

2. **Identifying Cork Composition**: Cork is primarily made up of dead plant cells. This is an important point because it indicates that the cells Hooke observed were not living.

3. **Analyzing the Options**:
- **Cellulose**: This is a carbohydrate that forms a part of the cell wall but is not a cell itself.
- **Living Cell**: Since Hooke observed dead cells in cork, this option is incorrect.
- **Cell Coat**: Also known as glycocalyx, this surrounds the cell membrane but is not what Hooke observed.
- **Cell Wall**: This is the outer structure of plant cells, composed of cellulose and lignin, and is present in the dead cells that Hooke examined.

4. **Conclusion**: The cells discovered by Robert Hooke in cork were actually part of the **cell wall**, which is made up of dead cells.

**Final Answer**: The cells discovered in thin sections of cork by Robert Hooke were actually **cell wall**.
