The document discusses how cell growth places increasing demands on a cell's DNA as it gets larger. If a cell grows without limit, it would soon experience an "information crisis" as its DNA could not adequately direct the large cell. As cells grow, their volume increases faster than their surface area, decreasing the ratio of surface area to volume, which controls how quickly materials can move in and out of the cell. To prevent becoming too large, growing cells undergo cell division, dividing into two new daughter cells.
