10-1 Section Assessment (pg 243 1-5)

1. Give two reasons why cells divide.
The larger a cell becomes, the more demands the cell places on it's DNA and the more trouble the cell has moving enough nutrients and wastes across the cell membrane.

2. How is a cell's DNA like the books in a library?
A cell is like a library because if a town grows bigger the deman for books is higher, and so the library gets more books. It is the same with a cell because if you get bigger the demand for more "books" is greater so the cell makes more.

3.What is the solution to the problems caused by cell growth?
they must divide as they grow

4. As a cell increases in size, which increases more rapidly, it's surface area or it's volume?
the volume increase much more rapidly

5. Calculate the surface area, volume, and ratio of surface area to volume of an imaginary cubic cell with a length of 4 cm.
The area of the surface is 96 cm cubed.
The volume is 64cm cubed.
