omer uner When living pancreatic cells were placed in a solution of a red stain called neutral red, the cytoplasm became red. The cells were then removed from the solution of neutral red.
The red stain in the cytoplasm moved into vesicles, which were exported from the cell, eventually leaving the cell colourless.
Which transport mechanisms could explain how the red stain entered and left the cells?
