Cells
Cells in multicellular organisms repeatedly divide to make more cells for growth and repair.
Item CE119002: The difference in size between young children and fully grown adults can be explained by the repetitive process of cell growth and division.
Fully-grown adults are much larger in size than young children. What happens to the cells of the body during the growth of a child?
- The cells of a growing child divide to make more cells, and those cells are each half the size as the cells were before they divided. The cells do not grow before they divide again.
- The cells of a growing child divide to make more cells, and those cells grow to become the same size as the cells were just before they divided.
- The cells of the body of a growing child grow, but the number of cells stays the same.
- The size and number of cells in the body of a growing child stay the same.
