Cell differentiation is the process by which cells become specialized and take on specific roles in an organism. nearly all cell types in a multicellular organisms contain the same dna, yet they express their genes differently. gene expression describes the way in which genetic information is put into action and influences how cells differentiate. what do you know about cell differentiation in multicellular organisms? check all of the statements that are true. proteins play a key role in cell differentiation. the external environment, specifically temperature, during the development of turtles and some other reptiles to determine the sex of hatching offspring different transcription factors are associated with the differentiation 
of stem cells into bone, muscle, 
and nerve cells. transcription factors bind to regulatory regions of a gene and affect their expression. the amount of available light or daylength to determine the 
patterns of gene expression 
that lead to flowering in some plants.
