Eukaryotic cells are more efficient than prokaryotes because their internal compartmentalization reduces overall cell size allows for specialization through merging of different tasks makes each compartment nutritionally independent of all others allows for specialization through the subdivision of particular tasks TRUE ANSWER : ? YOUR ANSWER : ?
