Explain the significance of the cell cycle.

• A. It allows for the exchange of gases in cells
• B. It is essential for cell growth, replication, and division
• C. It prevents mutations in DNA
• D. It regulates metabolic rates

Answer: (B)

The significance of the cell cycle lies in its crucial role in cell growth, replication, and division. The cell cycle is a series of phases that a cell goes through to grow and duplicate its DNA, followed by the division of the cell into two daughter cells. This process is vital for the maintenance of healthy tissues and for organismal development, as it enables organisms to grow from a single fertilized egg into a complex multicellular organism. Through the cell cycle, cells not only replicate their genetic material during the S phase but also ensure that each daughter cell receives an exact copy of the DNA during mitosis. This accurate replication process is essential for the continuation of life, as it allows cells to replace those that are damaged or dead, and supports the development of tissues and organs. While other processes like gas exchange, mutation prevention, and metabolic regulation are important to cellular function, they do not encompass the fundamental aspects of cell growth and division inherent to the cell cycle. Thus, the cell cycle is a critical framework for understanding how organisms develop and maintain their cellular structure.
