Yes, embryos contain totipotent cells, which are the earliest cells formed after fertilization. These cells have the ability to develop into any cell type in the body, as well as the extraembryonic tissues, such as the placenta. Totipotency is typically present in the first few cell divisions of the zygote, after which cells begin to differentiate into pluripotent cells, which can still form many, but not all, cell types.
a fertilized egg cell
Option a is false. Stem cells do not form totipotent embryos; they have the potential to differentiate into various cell types, but they do not have the ability to form a complete organism on their own.
Totipotent cells can differentiate into more types of cells
5-7 days embryonic cells are totipotent 6 week embryo cells are pluripotent
Totipotent stem cells are present in the earliest stages of embryonic development, specifically in the fertilized egg (zygote) and the first few divisions of the embryo. Therefore, the zygote contains the greatest number of totipotent stem cells. As development progresses, these cells differentiate into pluripotent and multipotent cells, losing their totipotency.

Option a is false. Stem cells do not form totipotent embryos; they have the potential to differentiate into various cell types, but they do not have the ability to form a complete organism on their own.
Pluripotent stem cells have the ability to differentiate into any type of cell in the body, including cells of the three germ layers: ectoderm, endoderm, and mesoderm. These cells are typically found in embryos and are also generated artificially in laboratory settings through techniques like induced pluripotent stem cell reprogramming.
Because it has totipotent cells. Totipotent cells are cells that are capable of developing into any type of cell
