Answer
b.
Work Step by Step
Option a. is incorrect. Embryonic stem cells are immortal in culture because they can divide infinitely.
Option c. is incorrect. Both adult and embryonic stem cells can differentiate when grown in a culture, depending on the conditions in which they are grown.
Option d. is incorrect. Embryonic stem cells are as easily grown in culture as adult stem cells.
Option b. is correct. Embryonic stem cells have more potential than adult stem cells. Adult stem cells are more differentiated; therefore, they can give rise to only several types of cells. On the other hand, embryonic stem cells are at an earlier stage of development and differentiation, so, in culture, they can give rise to different types of cells such as nerve cells and heart muscle cells.
