Part A: Rise of endomembrane system in the eukaryotic cells generally corresponds to the endosymbiotic oridin of mitochondria. Recent researches suggest that the endosymbiotic mitochondria used to secrete the outer membrane vesicles which in turn got evolved into the endomembrane system. Thus it suggest link of mitochondria to the compartment of the cell. part B: The sequnec of the events is : 1, 5, 4, 2, 3.
