Death By design: Cancer cells bypass Programmed cell death (PCD) and continue to divide and make a tumor. anything alive is a cell or made up of cells Plant cells look like square walls Animal cells look like soap bubbles what do cells do?: they regenerate themselves, they eat other cells, they do everything an animal can do. as the cells come together they form things we call plants and animals. How do cells communicate to each other? Cancer cells don't "listen" to signals

- Cells are suppose to kill themselves once they have run their course BUT cancer cells do not do this. - Cells are the unit of life How do the talk/communicate to each other? Cell death: Why make a cell if you re going to kill it
 * Leeuwenhock was the first person to see the cells by using a microscope.
 * Plant cells look like squares
 * animal cells look like soap bubbles
 * Cells can do everything an animal can do
 * cells form communities
 * There are different roles within the community of cells
 * Multicellular communities came later then the original unicellular organisms
 * Send a signal to each other BUT cancer cells dont listen to these signals.
 * Cells dont do anything unless they are signaled to do so.
 * for cells to stay alive they need signals from other cells to tell then to stay alive or they will kill themselves
 * if we put one cell in a dish- it will kill itself
 * PDC requires the cell to make molecules to kill itself
 * Cells start PCD when they are told so BUT cancer cells don't listen
 * Cells are based on evolution
 * humans evolved from creatures that were very different from us today, we were modified from what has come before
 * cant go back to the beginning and think of a more efficient process.
