Building blocks of life (5)

Ross

I believe the answer is:

cells

(Other definitions for cells that I've seen before include "Basic structural units of all organisms" , "terrorist groups" , "Small rooms" , "Accommodation for prisoners" , "Rooms for prisoners" .)

I've seen this clue in the Universal and the USA Today.
