What aspect of cell function involves moving substances and signals among organelles?

• apoptosis

• cellular communication

• mutation

• cytokinetic signals

The method by which a cell's cytoplasm divides is called ____.

• mitosis

• cytokinesis

Which of these is not an example of how substances move within cells?
