As any cell gets older, it is under attack by oxides and free-radicals in the body and environment. We survive as living beings because our cells have the ability to duplicate and replace themselves before being killed by these natural causes. Each time our cells divide, the DNA molecule ma...

In 2012, Integrative and Comparative Biology included 10 essays on various aspects of the impact of plasticity on evolution (...
"Carry on genes to the next generation" is a reasonable answer, but this is really more an attribute of cells than a function they perform. "Divide into two equal cells" is a defensible reply, too, but this is something cells by definition do at the very ends of their own lives, not...
