Which of the following facilitated the endosymbiotic acquisition of cyanobacteria that became modern chloroplasts? Question 1 options: ability of eukaryotes to carry out endocytosis similarity in biochemical pathways between chloroplasts and cyanobacteria reduction of cyanobacterial genome size conjugation between cyanobacteria and eukaryotic cell ability of eukaryotes to carry out endocytosis similarity in biochemical pathways between chloroplasts and cyanobacteria reduction of cyanobacterial genome size conjugation between cyanobacteria and eukaryotic cell Solution ability of eukaryotes to carry out endocytosis .... as cyanobacteria was endocytosed in endosymbiotic way it turned to chloroplast over an evolutionary time course .... this is called endosymbiontic theory.
