Cells grown in a petri dish tend to divide until they form a thin layer covering the bottom of the dish. Which of the following statements explains why this occurs?
A) The cells become deficient in cyclin.
B) The petri dish inhibits the cells' growth.
C) Cell division can be inhibited by the proximity of other cells of the same type, a process called contact inhibition.
D) Most cells grown in petri dishes have gone through apoptosis.
E) The cells have differentiated into more specialized cells.

Question

Quizplus · Accepted Answer

Cell division can be inhibited by the proximity of other cells of the same type through a process known as contact inhibition. This phenomenon helps to regulate cell growth and ensures that cells stop dividing once they form a complete layer, preventing overcrowding.
