What is a normal cell?

A normal cell is a standard unit of living matter that performs essential functions for an organism, such as growth, metabolism, and reproduction. It has a defined structure, including a cell membrane, cytoplasm, and organelles, each with specific roles. Normal cells follow the body's regulatory mechanisms, dividing and dying in a controlled manner, maintaining homeostasis and tissue integrity. In contrast, abnormal cells, such as cancer cells, may grow uncontrollably and disrupt normal physiological processes.
