see again the sentence that you've written...smallest unit of LIFE. so, if you said that chromosome is even smaller than cell, can it live by its own??

Cells need all of the subcellular orgalles TO LIVE!! (mitochondria, DNA, ribosomes, lysosomes, ER, cell membrane)....

However 99.99% of cells cant live with out it's organelles.. that's why a cell is considered the smallest unit of life (because it is composed of many organells in a small unit)
