These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

• Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.
