Detailed explanation-1: -Cellular differentiation occurs throughout development causing cells to take on their final form and physiology. The process through which unspecialized cells become specialised to perform certain functions is known as differentiation.

Detailed explanation-2: -In order for a cell to differentiate into its specialized form and function, it need only manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.

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

Detailed explanation-4: -Cell differentiation is an important process whereby a single cell gradually develops various tissues and organs. It helps in the development of an organism from a single cell zygote.

Detailed explanation-5: -Cell differentiation is caused by changes in gene expression. This occurs when different signaling molecules in the environment activate or repress different transcription factors that are necessary to express certain genes in the DNA. DNA is organized inside cells into chromosomes.
