What is the function of vesicles?

• A. Transport materials around the cell and to the cell membrane
• B. Manufacture ribosomes
• C. Break down waste
• D. Produce ATP

Answer: (A)

Vesicles are small membrane‑bound sacs that move materials around the cell and to the cell surface. They bud from one organelle, like the ER or Golgi, and fuse with another membrane to deliver their contents, so they’re essential for transporting and secreting proteins and lipids to their correct destinations. This also explains how substances can be released outside the cell or delivered to lysosomes for processing. By contrast, ribosome manufacture happens in the nucleus/nucleolus, waste breakdown occurs in lysosomes, and ATP is produced in mitochondria, not vesicles. Hence, transporting and delivering materials best describes the vesicle’s role.
