Answer :
The phenomenon that probably gives rise to the organelles in eukaryoptes is endosymbiosis
The term "endosymbiont" refers to a microbial cell that has established a stable home inside another microbial cells. According to the endosymbiotic theory, several organelles of eukaryotic cells are thought to be descended from endosymbionts. Studies of mitochondria and chloroplasts, which are assumed to have evolved from bacteria living in big cells, are particularly supportive of the idea that eukaryotic cells originated from an association of prokaryotes that engaged in endosymbiosis. The origin of eukaryotes and mitochondria. The origin of eukaryotic cells is explained by this idea. Chloroplasts and mitochondria are the same size as prokaryotic cells and divide through a process known as binary fission. In order to create the mitochondria and chloroplasts, an ancestral eukaryotic cell first had to internalize prokaryotes. This process is known as primary endosymbiosis.
