Cell theory states that life (cells) arise from non-life continuously. would be disproven (falsified) if one example of noncellular life were to be discovered. states that all organisms are composed of cells. states that all cells come from pre-existing cells. Question 2    1 / 1 point Although organisms have become quite large, in some cases, individual cells have remained quite small. This is because as cell volume increases, there is relatively less and less plasma membrane to service the interior of the cell. as cell size increases, its surface-area-to-volume ratio decreases. large cells would slosh around too much, like big water balloons. large organisms, like ourselves, have larger cells than do smaller organisms.
