Answer:
There would be no life (except for viruses [if they are considered to be alive]).
Explanation:
These cells are the "building blocks" of life, and all have RNA or DNA in them and a membrane around the outside. The only example of something "alive" without cells might be viruses (like what causes chickenpox or the flu) which are just packets of protein and DNA.
Answer:
Humans would not exist.
Explanation:
Cells make up tissues, tissues make up organs; without cells there are no tissues or organs. Without tissues organs, humans cannot exist.
