Are cells really the basic unit of all life?



Please see comments as to the appropriateness of this question on biology SE.


All known life on Earth is made up of cells. It is thus safe to say that all known life is characterized by the presence of cells. But is having cells as a basic unit a requirement for life?


I'm thus asking if life is currently existent and/or possible without biomembranes, and to what degree cells actually matter in our present understanding of life.


An all-encompassing, comprehensive and cited answer would be very much appreciated.
