CELL STRUCTURE AND COMPARTMENTS QUIZ

The highly folded membranes found in such eukaryotic organelles as mitochondria and chloroplasts

make it possible to package large amounts of DNA within the cell

increase the surface area where key chemical processes can occur

assist with cell movement

help the cell against physical damage

TRUE ANSWER : ?
YOUR ANSWER : ?

Eukaryotic cells are more efficient than prokaryotes because their internal compartmentalization

makes each compartment nutritionally independent of all others

allows for specialization through the subdivision of particular tasks

allows for specialization through merging of different tasks

reduces overall cell size
