63. Typically as cells grow, their increase in volume outpaces their increase in surface area, and continued survival requiresundergoing asexual reproduction to reestablish a healthy surface area to volume ratio. Thus, which of these is LEASTlikely to contribute to the ability of a single-celled foraminiferan to grow to a diameter of several centimeters?
(A) Its calcium carbonate test contributes extra mass.
(B) Its symbiotic algae provide glucose to the cytoplasm.
(C) Its symbiotic algae absorb metabolic waste products from the cytoplasm.
(D) Its symbiotic algae provide oxygen to the cytoplasm.
(E) Its threadlike pseudopods dramatically increase its surface area to volume ratio.
