Question 5
According to the first statement of the cell theory, what is the cell to life?
The right answer is the one marked above.
The structural unit and the functional unit alike. The cell is both the smallest piece a body is built from and the smallest piece in which the business of living gets done.
Picking just one of the two is the common slip. A brick is the structural unit of a wall but does nothing; a cell is more than that.
