What is the difference between embryonic stem cells and adult stem cells?

• Embryonic stem cells can differentiate into more cell types than adult stem cells

• Adult stem cells can differentiate into more cell types than embryonic stem cells
• Adult stem cells grow bigger than embryonic stem cells
