A multicellular organism typically begins as a single cell, and then many cell divisions occur to generate the cells of the adult organism. However, these cells are not identical to the original cell, and they are not identical to one another.

What is the most significant cause of cell differentiation in a multicellular organism?

A.
differences in the number of chromosomes per cell
B.
differences in the genetic code used by different cells
C.
differences in the DNA that is copied and distributed among the cells
D.
differences in gene regulation and gene expression among the cells

Difference in cell regulation and cell expression. This is embedded in chromosomes which is the blue print of the organism. The chromosomes is like the house plan when you building a house.

What is cell differentiation?

Cell differentiation can be defined as a process through which a young, unspecialized cell undergoes various changes in gene expression, so as to become a specialized that is more specific in terms of function.

In a multicellular organism, which is an organism with multiple cells, the most significant cause of cell differentiation is as a result of differences in gene regulation and gene expression among its cells.
