Detailed explanation-1: -These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
Detailed explanation-2: -Which is true about embryonic stem cells? They no longer divide; their cell type is set and cannot change.
Detailed explanation-3: -Which of the following is true of embryonic stem cells but not of adult stem cells? They can give rise to all cell types in the organism. embryonic stem cells can differentiate into more cell types than adult stem cells.
Detailed explanation-4: -Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. These cells are incredibly valuable because they provide a renewable resource for studying normal development and disease, and for testing drugs and other therapies.
Detailed explanation-5: -These germ layers generate each of the more than 220 cell types in the adult human body. When provided with the appropriate signals, ESCs initially form precursor cells that in subsequently differentiate into the desired cell types.
