Answer:
1- Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.
2- To keep cell damage to a minimum, we need to reduce free radical damage. This can be done with better nutrition (more antioxidants), less stress, more exercise, no smoking, and some important herbs and supplements.
3- No because Cells are one of the characteristics we use to define whether something is alive or not... The only example of something "alive" without cells might be viruses (like what causes chicken pox or the flu) which are just packets of protein and DNA.
