Quizplus · Accepted Answer

A protocell is a hypothetical and primitive cell-like structure that is believed to have arisen spontaneously from non-living matter on early Earth. It is composed of a membrane-bound compartment that contains interacting molecules, which can carry out some of the basic functions of life, such as metabolism and replication. The protocell is thought to have been a precursor to the first living cells and may have been able to evolve into more complex organisms over time. The other options (B) archaea, (C) ribozyme, (D) chemotroph, and (E) protist, do not refer to the specific structure described in the question.
