Vesicles can be compared to courier services such as Fedex. They are simply the transporters of substances to and from the Golgi Apparatus, into and out of the cell.
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
These are called vesicles and they transport various substance into the cell and out of the cell.

Well, darling, we've got primary active transport where molecules move against the concentration gradient using ATP, secondary active transport where molecules hitch a ride with another molecule moving down its gradient, and finally, good old vesicular transport where large molecules are engulfed by a vesicle and transported across the cell membrane. Hope that clears things up for you, sugar.
Vesicular active transport
No, vesicular transport and solute pumps are two different mechanisms. Vesicular transport involves the movement of materials within vesicles, while solute pumps use energy to actively transport solutes across a cell membrane.

Vesicular active transport
Yes, phagocytosis is an example of vesicular transport. It is a process in which cells engulf large particles or other cells by forming a vesicle around the material and bringing it into the cell for digestion or processing.
Vesicular transport is an active process in which materials move into or out of the cell enclosed as vesicles. Vesicles are bubble-like structures surrounded by a membrane. They can form at the cell membrane or can fuse with the membrane. Solid particles, droplets of fluid or many molecules at a time can be moved across the membrane in vesicles. Vesicular transport is also known as bulk transport because large quantities of materials can be transported in this way. Th ere are two basic types of vesicular transport-endocytosis and exocytosis.
Exocytosis is the vesicular transport method that expels material from the cell. It involves the fusion of vesicles with the plasma membrane, releasing their contents outside the cell.
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
Cells utilize various types of transport mechanisms to move substances across their membranes, including passive transport, active transport, and vesicular transport. Passive transport, such as diffusion and osmosis, does not require energy and relies on concentration gradients. Active transport requires energy to move substances against their concentration gradients. Vesicular transport involves the formation of vesicles to transport large molecules or particles into (endocytosis) or out of (exocytosis) the cell.
These are called vesicles and they transport various substance into the cell and out of the cell.
