Cellular Activity

     Cells are needed for ANY and EVERY living things that exists. That includes us, human beings. But how do we know that our cells are functioning correctly if we cannot feel the cellular activity going on inside our bodies? Well, it's simple actually. We know that cells are not visible to the naked eye, so that means they are very small. That also means that you probably can't feel those small things functioning inside your body. Also, you know that your cells are functioning correctly if you are alive. Because remember, cells are one of the many things that help keep you alive. That means that your cells are obviously functioning the way that they are supposed to be. So, to sum this all up, you know your cells are functioning if you are alive.
