Chapter 1.3 The Cell Cycle
Clearly mitosis and cell division cannot completely explain how two cells (a sperm and an egg) can divide and form into an organism
composed of 60 trillion cells. Our bodies are made up of many types of cells, each doing a specific job as a result of cell
specialization. This, among other things is the topic of chapter 1.3.
Using figure 1.14 as a guide, explain the levels of specialization that are evident in a human.
