How do large, mature plant cells compensate for inefficient import and export associated with a lower surface area-to-volume ratio? a. Large plant cells have increased lysosomic activity to increase import and export of substances to and from the membrane. b. Large plant cells have a large water-filled vacuole in the center, decreasing the active cytoplasm volume. c. Large plant cells have adapted a more efficient metabolic system, whereby fewer nutrients are needed for the structures located at the center of the cytoplasm. d. Large plant cells maintain a large storage vacuole in the center that stores nutrients for use in the interior of the cytoplasm.
