YOUR ANSWER : ?

Which of the following statements about prokaryotes is false?

The substance known as cytosol is found within the bacterial nucleus

Prokaryotic cells concentrate important materials for the cells survival

Ancient prokaryotes may have given rise to some eukaryotic organelles

Prokaryotic cells are much smaller than most eukaryotic cells

TRUE ANSWER : ?
YOUR ANSWER : ?

Eukaryotic cells are more efficient than prokaryotes because their internal compartmentalization

allows for specialization through the subdivision of particular tasks

reduces overall cell size

makes each compartment nutritionally independent of all others

allows for specialization through merging of different tasks
