Consider the following statements about cells with a membranous envelope. (1) The mechanism of how non-cellular aggregates of giant macromolecules could evolve into cells with membranous envelope is not known. (2) Some of these cells had the ability to release O₂. (3) The reaction could have been similar to the light reaction in photosynthesis where water is split with the help of solar energy captured and channelised by appropriate light harvesting pigments.
