Protocells biology
Webb16 sep. 2024 · Protocells are self-organized micro- or nano-sized compartments, which are considered as intermediate structures between non-living weakly structured precursors, and living cells. Protocells are not as dispersed as a liquid medium, but they are also not as well-organized as modern biological cells. Where do protocells get their energy from?
