Q

Normal cells vs. Cancer cells (Normal)
Specialized:
Reproduction:
Communication:

Adhesion:

Death:

A

Normal
*Specialized functioning cells differentiated
Reproduce in a controlled manner
*Communicate w/other cells using chemicals singles, cell inhibition
*Cells have molecules which allow them to stick to other cells thus helping the cells stay in an organized arrangement
*Cells can self destruct when they become damaged or diseased

41
Q

Normal cells vs. Cancer cells (Cancer cells)
Specialized:
Reproduction:
Communication:

Adhesion:

Death:

A

Cancer Cells

  • Specialized immature cells, undifferentiated
  • Reproduce uncontrollably
  • Lose the ability to communicate with other cells through chemical signals, loses cell inhibition
  • Lose the molecules that aid in adhesion more easily allowing the cells to break off and spread to other areas of the body
  • Cells lose their ability to self destruct when damaged
