The joining. of an egg and a sperm is called fertilization, and the cell that. forms is called a zygote (ZI goht). Generally, the egg and the. sperm come from two different organisms of the same species. Following fertilization, mitosis and cell division begins. A new. organism with a unique identity develops.
This marks the end of mitosis. As a result of mitosis, the cell now contains two identical nuclei. In order to make two cells, cytokinesis must take place. Cytokinesis is the division of the cytoplasm and generally starts during telophase of mitosis. The visible indicator of the start of cytokinesis is the formation of the cell plate along the equator of the dividing cell.
