Identify three pieces of evidence for endosymbiotic theory by identifying three similarities between mitochondria and the ancestral species. During exocytosis, vacuoles prepare some molecules to release signals that will be received by other cells, which will retrieve those molecules. While plant vacuoles are easily identifiable because of the large amount of space they take up inside the cell, animal cells would not benefit from a large central vacuole.
