WebSep 29, 2009 · In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though. WebWatch on. A malignant tumor, also known as a cancerous tumor, starts when normal cells begin to grow out of control, leading to the formation of abnormal tissue. This uncontrolled growth occurs due to mutations or changes in the DNA of the cells, which disrupt the normal cell cycle process, causing them to divide and grow rapidly. information technology in steel industry
