Detailed explanation-1: -Eobionts are hypothetical primordial life-form or chemical precursor to a living organism. The coacervates got transformed into the primitive living systems, which have been called as, protobionts or eobionts. These are the first formed cells. So, called as, pre cells or protocells or protobionts.

Detailed explanation-2: -Thus, coacervates represent the protocell model and an open system that keep accumulating materials from their environment., which is a characteristic feature of a living cell. Hence, coacervates are considered primitive cells.

Detailed explanation-3: -Among all kinds, coacervates formed by liquid-liquid phase separation featured by their dynamic structure, molecularly crowded interior and molecular sequestration capability, have been regarded as a protocell model for exploring the origin of life.

Detailed explanation-4: -Coacervates in biology Membraneless organelles (MLOs), also known as biomolecular condensates, are a form of cell compartmentalization. Unlike classic membrane-bound organelles (e.g. mitochondrion, nucleus or lysosome), MLOs are not separated from their surroundings by a lipid bilayer.

Detailed explanation-5: -Analogous to membraneless organelles, complex coacervates are water droplets dispersed in water and formed by spontaneous LLPS of an aqueous solution of two oppositely charged polyelectrolytes to form a dense polyelectrolyte-rich phase (coacervate) and a more dilute solution (Fig. 1).
