Answer Choices:
Correct Answer:
Develops into any kind of cell
Rationale:
◈ A totipotent cell has the ability to differentiate into all cell types, including both embryonic and extra-embryonic (placental) tissues.
◈ The zygote and the first few divisions of cells after fertilization are totipotent.
◈ These cells are capable of forming a complete, viable organism, making them the most versatile stem cells.
◈ As development progresses, cells become pluripotent or multipotent, limiting the types of cells they can become.
