Final answer:
Cell division is essential to repair and replace damaged or worn-out cells, ensuring organism growth, and maintaining health by producing new cells with accurate DNA replication.
Step-by-step explanation:
The significance of cell division is to repair and replace other cells (C). This process is crucial for various reasons, including the growth of an organism, the development of an embryo, and the maintenance of an individual's health. Cell division allows our bodies to replace cells that are damaged, worn out, or have completed their life cycle. For instance, when you injure yourself, such as cutting a finger, your existing skin cells divide to produce new cells for wound repair. Similarly, cells lining the gastrointestinal tract must be frequently replaced due to wear and tear from food movement.
DNA replication is a vital step before cell division to ensure that each new 'daughter' cell receives the complete genetic information required for proper functioning. Without accurate DNA replication before cell division, cells might not function as intended, leading to various problems, including the potential for disease.
