 * __Death by Design__**

cell suicide Cancer cells bypass (pcd)

Cell:the ultimate unit of life continue to divided and make a tumor Leeuwenhoek- invented the first telescope

plant cells look like rooms and animal cells look more like bubbles.

what do cells do? anything an animal can do

cells come together and become "Community Cells" each cell has a different role in the community of cells multicellular communities came much later (during evolution)

how do cells talk to eachother?
 * they send signals to one another (cancer cells dont "listen" to the signals)
 * cells dont do anything unless they are signaled to do so
 * move, grow, divide! dont divide!

any ONE cell is listening to hundreds of signals at one time

put one cell in a a dish- it dies, it kills itself
 * neat death
