AP BIOLOGY

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: -Stem cells are undifferentiated or “blank” cells that have not yet fully specialized. Under proper conditions, stem cells begin to develop into specialized tissues and organs. Additionally, stem cells can self-renew, that is they can divide and give rise to more stem cells.

Detailed explanation-3: -Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells.

Detailed explanation-4: -Oligopotent: These can differentiate into a few different cell types. Adult lymphoid or myeloid stem cells can do this. Unipotent: These can only produce cells of one kind, which is their own type.

Detailed explanation-5: -Adult stem cells are unspecialised but can become specialised much later than embryonic stem cells. They can differentiate into related cell types only. For instance, adult stem cells in the bone marrow can differentiate into blood cells and cells of the immune system, but not other cell types.
