Answer
Exocytosis is the process by which cells expel materials. This is typically achieved through the fusion of vesicles containing the material with the plasma membrane, releasing it outside the cell. If Process R involves expelling substances, this would be the correct choice.
Step 2

Answer
Phagocytosis refers to the process of engulfing large particles or cells. It is a type of endocytosis generally used by immune cells to consume pathogens. Process R does not imply this mechanism.

Answer
Endocytosis is a broad term for the processes by which cells internalize substances. If Process R involves the intake of substances, this option could be considered. However, without additional context indicating internalization, this would not be the best choice.
