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.
Totipotent stem cells are found in the very early stages of embryonic development, specifically in the fertilized egg (zygote) and the first few cell divisions. Among the options typically provided, the zygote contains the greatest number of totipotent stem cells, as it has the potential to develop into any cell type in the body, including extraembryonic tissues. As development progresses, cells become more specialized and lose their totipotency.

The greatest number of unipotent stem cells is typically found in tissues with high regenerative capacity, such as the skin and the lining of the gastrointestinal tract. These tissues contain specialized unipotent stem cells that are responsible for the continuous renewal and repair of specific cell types. For example, in the skin, epidermal stem cells give rise to keratinocytes, while in the gut, intestinal stem cells generate various types of intestinal epithelial cells.
Totipotent stem cells are primarily found in the earliest stages of embryonic development, specifically in the zygote and the first few divisions of the embryo, up to the 8-cell stage. These cells have the potential to develop into any cell type in the body, including both embryonic and extraembryonic tissues. After this stage, cells become pluripotent, meaning they can differentiate into almost any cell type but cannot form an entire organism. Therefore, the greatest number of totipotent stem cells is present in the very early embryo, particularly before the 8-cell stage.
