Explanation:

Statement 1 is correct: Pluripotent cells can be specialised into all cell types that make up the body. Embryonic stem cells are considered pluripotent.

Statement 2 is correct: Stem cells are pluripotent stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

Statement 3 is correct:
  • Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo.
At this stage, an embryo is called blastocyst and has around 150 cells.
