Detailed explanation-1: -Cell differentiation describes the process of specialization leading to the formation of brain, heart, and all other tissues from the single-cell zygote and the primitive, three-layered embryo.

Detailed explanation-2: -The differentiation of cells during embryogenesis is the key to cell, tissue, organ, and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.

Detailed explanation-3: -Cell specialization, also known as cell differentiation, is the process through which “generic” or “common” cells transform into specialized cells with defined tasks. Generic embryonic cells differentiate into specialized cells through cell differentiation.
