Why do we need cells to live?
Answer 1:

We are cells; everything that makes the human body are cells. All the tissues and organs in our bodies are made up of cells. We are made up of billions of these cells, which help in reproduction, growth, eliminating toxins, and keeping our bodies healthy. All cells do not serve the same function, however. Some cells are blood cells, some serve to help with reproduction, some with metabolism, and many more. Cells constantly die and new cells are made. If there weren't cells, we would not exist.

If you take a cotton swab and swab the inside of your mouth there will be cheek cells on the cotton swab. When you brush your hands together or brush something off of your arms, cells get brushed off also. They are so tiny that they can only be seen under a microscope. If cells themselves are so tiny, imagine how tiny the organelles that make up the cells are, but they still serve vital functions in our bodies that keep us alive. The human body is miraculous in this way.
