The two different hypotheses of the origin of early cell structure are the iron-sulfide bubbles hypothesis and the lipid membrane hypothesis
Explanation:
The iron-sulfide bubbles hypothesis by William Martin and Micheal Russel originated from small-sized compartments formed with iron sulfide bubbles which were lying on the ocean floor. These compartments had organic matter trapped inside them and which developed further and started to be bounded by their own cell membrane.
The lipid membrane hypothesis by Harold Morowitz proved that liposomes with the double lipid membrane formed organic material and could be separated from the environment. This theory stated that the cells were formed by the surrounding organic molecules
