in organisms, most cells are specialized, meaning that each type of cell has a unique structure & function
each cell in an organism has a special job
all cells start out the same way, as

stem cells are cells that are not yet
they do not yet have a specific
they are (not yet different)

Explanation:

All cells in an organism have the same DNA. Different genes (sequences of DNA) are turned on or off to make different proteins, which give cells unique structure and function. Cell - differentiation is the process of turning genes on or off to change cell behavior. In multicellular organisms, most cells are specialized. All cells start as stem cells. Stem cells receive signals to become different cell types. Stem cells are undifferentiated, have no specific function yet, and are identical at the start.

Answer:

How are all cells in an organism the SAME?: DNA
How are cells in an organism DIFFERENT?: genes, on/off, proteins
different proteins help each type of cell in the body to have a unique structure & function
Cell - differentiation: the process of turning different genes on or off to make cells act differently
as cells become differentiated, they become specialized
in multicellular organisms, most cells are specialized
How do cells become SPECIALIZED?: stem cells
the stem cells receive signals that tell them to become all different cell types of the body
What is a STEM CELL?: undifferentiated
they do not yet have a specific function
they are identical (not yet different)
