During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells, each of which then begins the cycle again. During division there are two stages: mitosis and cytokinesis. In mitosis, there are four stages: prophase, metaphase, anaphase, and telophase, and in cytokinesis, the cell finally divides. 12. The larger a cell becomes, the more demands it places on the DNA. As a cell increases in size, it usually does not make copies of DNA. If a cell were to grow without limit, and information crisis would occur. In time, the cell’s DNA would no longer be able to serve the increasing needs of the growing cell. 13. Cell volume is the amount of cellular materials inside the cell, and affects the rate at which food and oxygen are used up and waste products are produced. Cell surface area is the total area of the cellular membrane and affects the rate of the exchange between waste products, food, and oxygen. The ration of surface are to volume shows that as a cell grows, its volume increases
