vesicles

Vesicles are tiny, bubble-like structures within cells that act as containers, transporting molecules such as proteins, fats, and waste materials between different parts of the cell or to the outside environment. They are surrounded by a membrane similar to the cell membrane, which helps them merge with other membranes to deliver their contents precisely where needed. Vesicles play essential roles in processes like nutrient uptake, waste removal, and cell communication, functioning much like delivery trucks within the cell to ensure materials move efficiently and accurately.
