The diagram shows the process of cell specialization from a single stem cell. Which of the following statements is true about the process of specialization.

• Specilized cells (blood, skin, nervous etc) cannot be produced from a single stem cell
• Specilized cells are produced immediately following fertilization
• Even though all the cells in an organism come from one single cell, they can specialize into different cell types
• Sincce all the cells in an organism come from one single cell, they must all have the same structure and function
