Final answer:
If the cells of a tree seed do not differentiate, all of the cells would be identical and the seed would not be able to form different tissues and structures required for the growth of a tree.
Step-by-step explanation:
When the seed of a tree first starts to grow, if the cells did not differentiate, all of the cells would be identical. Differentiation is the process where cells become specialized to perform specific functions in the organism. Without differentiation, the seed would not be able to form different tissues and structures necessary for the growth of a tree, such as roots, stems, leaves, and flowers.
