Final answer:
When cells divide excessively, they may form a tumor, leading to cancer, which occurs when the cell cycle is no longer regulated and cells grow out of control.
Step-by-step explanation:
When cells divide more than they are in interphase, the potential result can be the development of a tumor, which is a mass of abnormal cells. This uncontrolled cell division is characteristic of cancer, a disease where the regulatory mechanisms of the cell cycle are compromised. Cancer cells often divide much faster than normal cells, take up vital nutrients and space, and can cause damage to tissues and organs. Mutations in genes that control the cell cycle, like those for cyclin proteins, can lead to this uncontrolled proliferation. It's important to understand that not all growth is healthy or normal, as excessive and disordered growth can lead to serious health issues such as cancer.
