the structural and functional unit of life called cell was discovered by

Options

A. robert boyle
B. charles darwin
C. robert koch
D. robert hooke

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the discovery of the cell, which is known as the structural and functional unit of life.

2. **Identifying the Scientists**: The options provided are Robert Boyle, Charles Darwin, Robert Koch, and Robert Hook. We need to analyze the contributions of each to determine who discovered the cell.

3. **Evaluating Robert Boyle**: Robert Boyle was a renowned physicist and chemist known for his work in those fields. However, he did not make any significant contributions to biology or the discovery of cells. Thus, he is not the correct answer.

4. **Evaluating Charles Darwin**: Charles Darwin is famous for his theory of evolution and natural selection. While he made significant contributions to biology, he did not discover the cell. Therefore, he is also not the correct answer.

5. **Evaluating Robert Koch**: Robert Koch was a prominent microbiologist known for his discoveries related to infectious diseases, such as tuberculosis and cholera. However, he did not discover the cell, making him an incorrect option as well.

6. **Identifying Robert Hook**: Robert Hook was a biologist and an architect who made significant contributions to the field of microscopy. He created a compound microscope and was the first to observe and describe cells. He named them "cells" because they resembled the small compartments of a jail.

7. **Conclusion**: After evaluating all the options, the correct answer is Robert Hook, as he is credited with the discovery of cells.

**Final Answer**: The structural and functional unit of life called cell was discovered by Robert Hook.
