What is life: self replication: we can reproduce, self regulation: ability to control and regulate our environment - homeostasis, if we are hot, we sweat, if we are cold, we shiver. *prokaryote cell - cells that are in bacteria - earliest form of life that we know about.

Each cell contains an organ that perform different functions. Strong enough that you can sit on it. It has to have a seat part and a back part.
