Explanation: Cell A is bacterium, prokaryotic while cell B is eukaryotic. Eukaryotic cells are bigger cells than prokaryotic cells thus the internal volume enlarge and the total cell membrane expands. Therefore, the ratio of total cell membrane to volume of cell A is not higher than that of the ratio of total cell membrane to volume of cell B.
