NEET BIOLOGY

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: -One of the major areas of research in biology is of how cells specialize to assume their unique structures and functions, since all cells essentially originate from a single fertilized egg. Cell differentiation is the process of cells becoming specialized as their body develops.

Detailed explanation-3: -(sel DIH-feh-REN-shee-AY-shun) The process during which young, immature (unspecialized) cells take on individual characteristics and reach their mature (specialized) form and function.

Detailed explanation-4: -Embryonic differentiation is the process of development during which embryonic cells specialize and diverse tissue structures arise. Animals are made up of many different cell types, each with specific functions in the body.

Detailed explanation-5: -The embryonic stage lasts through the eighth week following fertilization. During this time, the embryo grows in size and becomes more complex. It develops specialized cells and tissues and starts to form most organs.
