Final answer:
Cell division benefits the human body by enabling growth, tissue repair, and replacement of worn-out cells.
Step-by-step explanation:
Cell division benefits the human body in several ways:
- Growth: Cell division allows the human body to grow and develop from a fertilized egg into a complex multicellular organism. Trillions of cell divisions occur in a controlled manner to produce all the different cells in the body.
- Tissue Repair: Cell division is necessary to repair damaged cells. When you cut your finger, existing skin cells divide and produce new cells to replace the damaged ones.
- Replacement of Worn-out Cells: Over time, old and worn-out cells need to be replaced. Cell division is essential for this process, as it produces new cells to replace the worn-out ones.
