Differentiate totipotent, pluripotent and multipotent stem cells.
Totipotent stem cells are the most versatile cells capable of producing both the embryo and extra-embryonic membranes to form an entire functional organism. For example, a zygote has this potential. These cells belong to the embryonic life of the organism.
Pluripotent stem cells can differentiate into almost all cell types of the embryo except extra-embryonic support tissues like the placenta. Therefore, they cannot form a complete organism. They originate from the inner cell mass of the blastocyst and give rise to all germ layers.
Multipotent stem cells differentiate into a closely related family of cells within a specific lineage. Found in adult life, these cells are more restricted; for example, hematopoietic stem cells can only develop into various types of blood cells.
Explanation
The answer differentiates the three stem cell types based on their differentiation potency and sources as described in the NCERT textbook. Totipotent cells have the highest potency (zygote), Pluripotent cells form all embryonic tissues but not extra-embryonic tissues (embryonic stem cells), and Multipotent cells are restricted to a specific lineage (adult stem cells).
