Detailed explanation-1: -"The exterior structure similar to bacterial cell walls” IS NOT an evidence in favour of the endosymbiotic theory.
Detailed explanation-2: -The endosymbiotic theory for the origin of the nucleus started with Mereschkowsky [13]. He postulated that the nucleus evolved from a prokaryote (mycoplasma), which was engulfed by an amoeboid cell homologous to the eukaryotic cytosol (figure 1a; [15]).
Detailed explanation-3: -So, the correct answer is ‘The presence of membrane proteins on prokaryote cell membrane’.
Detailed explanation-4: -Evidence for Endosymbiosis Evidence that supports the extracellular origins of these organelles can be seen by looking at certain key features: Membranes (double membrane bound) Antibiotics (susceptibility) Division (mode of replication)
