- Facilitated diffusion
- Endocytosis
- Active transport
- All answers are false
Correct answer
Exocytosis
Explanation
Exocytosis is an important process of plant and animal cells as it performs the opposite function of endocytosis. In endocytosis, substances that are external to a cell are brought into the cell. In exocytosis, membrane-bound vesicles containing cellular molecules are transported to the cell membrane. Therefore, Exocytosis is a form of active transport and bulk transport in which a cell transports molecules out of the cell by expelling them through an energy-dependent process.
