As a cell becomes larger it's ?

• volume increases faster than its surface area

• surface area increases faster than its volume

• volume increases,but its surface area stays the same

• surface area stays the same,but its colume increases

if the surface area of a cell increses 100 times ,its volume increases about

• 5 times

• 10 times

• 100 times

• 1000 times

The rate at which wastes are produced by a cell depends on the cell's

• ratio of surface area to volume

• enviroment

• volume

• surface area

All of the following are problems that growth causes for cells except

• DNA overload

• excess oxygen

• obtaining enough food

• expelling wastes

Compared to small cells ,large cells have more trouble

• dividing

• producing daughter cells

• moving needed materials in and waste products out

• making copies of their dna

The process by which a cell divides into two daughter cells is called

• cell division

• metaphase

• interphase

• mitosis

Which of the following is NOT a way that cell divsion solves the problems of cell growth

• cell division provides each daughter cell withs it own copy of DNA

• cell division increases the mass of the original cell

• cell division increases the surface area of the original cell

• cell division reduces the original cells volume

If a normal cell divides,you can assume that

• its surface are has become larger than its volume

• its volume has become larger than its surface area

• it has grown to its full size

• it has grown too large to meet its needs

If a cell's DNA were not copied before cell division,the cell could

• have a DNA overload

• become cancerous

• fil to exchange materials

• divide

which of the following happens when a cell divides?

• the cell's volume increases

• it becomes more difficult for the cell to get enogh oxygen and nutrients

• the cell DNA overload

• each daughter cell receives its own copy of the parents cell's DNA
