They therefore lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane. Viruses make up less than 1% of all forms of life while about 90% of all cells are bacteria (presumably because they produce proteins). Cellular organisms are found in the body or inside cells, while acellular organisms are not found in the body. Non-cellular life refers to organisms, such as viruses, that exist without any cells, and it is a very controversial topic. Multicellular Organisms.
