Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is cell differentiation?
A
The process where unspecialized cells become different in structure and function.
B
When DNA controls the cell cycle.
C
The ability of cells to make more cells.
D
The ability of cells to maintain homeostasis.
Explanation: 

Detailed explanation-1: -Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

Detailed explanation-2: -Listen to pronunciation. (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-3: -Cell differentiation is known as a process in which cells become specialized. Pluripotency means the potential to become any cell type and is a potential observed in stem or progenitor cells at the beginning of the differentiation process.

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.

Detailed explanation-5: -To summarise: Unspecialized cells become specialised by external stimuli that alter gene expression-turn some genes on and some off. Following transcription and production of the mRNA, translation produces proteins that are able to determine the cell’s structure hence function.
