According to the endosymbiont hypothesis, a. most of the genes from the endocytosed bacteria moved to the nucleus b. most of the genes from the endocytosed bacteria moved to the nucleus, the host anaerobe became dependent upon the endocytosed bacteria, and the endocytosed bacteria became dependent on the host cell c. the host anaerobe became dependent upon the endocytosed bacteria d. all endocytosed bacteria were photosynthetic e. the endocytosized bacteria became dependent on the host cell

The correct answer is: b. most of the genes from the endocytosed bacteria moved to the nucleus, the host anaerobe became dependent upon the endocytosed bacteria, and the endocytosed bacteria became dependent on the host cell  

Endosymbiotic theory explains the origin of eukaryotic cells from prokaryotic organisms, more precisely, the origin of eukaryotic organelles from prokaryotic organisms. According to this theory, eukaryotic cell (amoeba-like) ingested prokaryotic cell  that survived within it and they even developed a symbiotic relationship (they became dependent on each other). For example, mitochondria was formed from the bacteria capable of aerobic respiration. So, mitochondria, plastids (chloroplasts), and possibly other eukaryotic cells’ organelles are “consequence” of endosymbiosis.
