Answer :
Final answer:
The cause of cell differentiation is that different cells express alternate genetic information, not that they contain different DNA or chromosomes or contain similar protein information. This is what makes each type of cell unique.
Explanation:
The cause of cell differentiation is that different cells express alternate genetic information.
All cells in an organism contain the same DNA and chromosomes, but they can become different types of cells because they activate or 'express' different sets of genes.
This is what leads to cell differentiation, where each type of cell has a specialized function. For example, a skin cell expresses different genes than a muscle cell or a nerve cell, making it look and function differently.
