O cell wall and cell membrane O cytoplasm and cell membrane O cell (sap) vacuole and cell wall O chloroplast and cytoplasm1. A scientist synthesized a membrane in the laboratory. The synthetic membrane has allthe properties associated with the cell membranes of living cells, can spontaneously formspheres or bubble-like configurations, which replicate on their own, and react with stimuliin the environment. With these findings, the scientist claims he was able to re-createunder laboratory conditions, what Earth’s first living cells possibly look like. State andbriefly explain/support your opinion about his claim. 2.
