An adult has more cells, not bigger cells, than an infant has. Explain why this is so.

New babies are both very like and very unlike adults. Most cell development and differentiation occur prior to a baby's birth, and baby stem cells, cells that can become different types of tissue, are essentially the same as adult stem cells. The cells and tissues of a baby are different from those of an adult, though. Babies need to survive outside the womb, grow, develop and adapt to the world to become fully functional adults, and the differences in their cells reflect this.
