Answer: The correct answer for the blank is-
Cell.
Cell is the smallest biological, structural, and functional unit of all life forms ( such as plants, animals, and bacteria). In other words it is the basic unit of all life forms as all the living organisms are composed of cell.
Cell can exist independently and performs all the cellular processes ( metabolic processes) that are necessary for the survival.
Thus, cell is the right answer.
