- Both cellular waste and secretions are expelled by the cell for communication with other cells.
- Cellular waste is produced as a byproduct of metabolic reactions, while secretions are released by cells to perform specific functions.
- Cellular waste is stored in vesicles, while secretions are immediately broken down within the cell.
- Secretions are only produced by prokaryotic cells, while waste is produced by all cell types.
