The cell theory is one of the fundamental concepts in biology. It states that all living organisms are made up of cells, which are the basic units of life.

This theory was developed over several centuries by numerous scientists, and it has answered some critical questions about life on earth. In this article, we will discuss the three important questions that were answered by the cell theory.

What is the structure of living organisms?

Before the development of the cell theory, people did not have a clear understanding of what living organisms were made up of. Some believed that organisms were made up of a single substance, while others believed that they were composed of complex structures. However, with the discovery of cells, it became clear that all living organisms are made up of one or more cells.

How do living organisms function?

Another important question that was answered by the cell theory is how living organisms function. Cells are responsible for carrying out all the functions necessary for an organism’s survival. They divide to create new cells, use energy to perform work, and respond to changes in their environment.

How do living things evolve?

Finally, the cell theory has shed light on how living things evolve over time. All living organisms have DNA that contains genetic information that is passed down from one generation to another.

As cells divide and reproduce, they pass on this genetic information to their offspring. Over time, mutations can occur in DNA, leading to new traits and characteristics in offspring.

In conclusion, the cell theory has answered some critical questions about life on earth. It has given us insight into how living organisms are structured and function and has helped us understand how they evolve over time. With this knowledge in hand, scientists can continue to study cells and gain a deeper understanding of life itself.
