The membrane bound sac formed from the smooth endoplasmic reticulum is called the cisterna. It refers to the part of the ER that is studded with ribosomes.

A vacuole is a membrane-bound sac mainly used for storage within plant cells. It helps store nutrients, water, and waste products, maintaining the cell's turgidity and regulating its internal environment.
A small membrane-bound sac used to transport cellular chemicals is called a vesicle. Vesicles help transport molecules between different cellular compartments and play a key role in maintaining cellular organization and function.
When substances are too large to pass through the cell membrane directly (they'd leave a gaping hole), they are enclosed in a lipid sac that is similar in composition to the cell membrane. Instead of punching through the membrane, the sac merges with it allowing the large substance to exit the cell without damaging the membrane.

If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
The membrane sac formed by pinching off pieces of cell membrane is called a vesicle. Vesicles are used for intracellular transport of proteins and other molecules within the cell.

These are called vesicles and they transport various substance into the cell and out of the cell.
