Detailed explanation-1: -Stem cells are unspecialized cells that have not yet “decided” what type of adult cell they will be. They can self-renew and make two new stem cell. They can differentiate to make multiple types of cells. They ultimately amplify by expanding the number of differentiated & mature cells.

Detailed explanation-2: -Stem cells are unspecialized. For example, a stem cell cannot work with its neighbors to pump blood through the body (like a heart muscle cell), cannot carry oxygen molecules through the bloodstream (like a red blood cell) or carry impulses (like nerve cells).

Detailed explanation-3: -parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.

Detailed explanation-4: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal. Stem cells exist both in embryos and adult cells. There are several steps of specialization.
