This has to do with SURFACE TO VOLUME RATIO. For a typical small cell, its surface area to the volume ratio get smaller as the cell grows. This implies that, if the cell grows beyond a certain limit, then the amount of nutrients that entered the cell will be limited, that is , nutrients will not be able to migrate into the cell as needed. To avoid this, the cell has to divide to reduce its surface to volume ratio.<span />
Answer:
true
