CELL STRUCTURE AND COMPARTMENTS QUIZ

Eukaryotic cells are more efficient than prokaryotes because their internal compartmentalization

allows for specialization through the subdivision of particular tasks

allows for specialization through merging of different tasks

reduces overall cell size

makes each compartment nutritionally independent of all others
