As a cell becomes larger, its

• Volume increases faster than its surface area

• Surface area increases faster that its volume

• Volume increases, but its surface area stays the same

• Surface area stays the same, but its volume increases

Which of the following explains why normal cells grown in a petri dish tend to stop growing once they have covered the bottom of the dish?

• The cells lack cyclin

• The petri dish inhibits cell growth

• Contact with other cells stop growth
