Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
Contractile vacuoles pump excess water out. This makes them different from other types of vacuoles. A contractile vacuole is a sub-cellular structure.
no?
I know of only three types: central vacuole - helps maintain plants' shape and structure by storing water (hypotonic). contractile vacuole - pumps water out of protist cells to maintain a suitable concentration. food vacuole - storage for molecules that is a food source for the cell (phagocytosis).
The Contractile Vacoule.
In plant cells there is 1 large vacuole that acts as the main water source for the plant. In animal cells, there are multiple small vacuoles scattered throughout the plant that act as water sources also.
Vacuoles are involved in the process of ingestion. Pockets can form along the cell membrane and can pinch in to form vacuoles. The contents of the vacuoles can eventually by digested by lysosomes.

contractile vacuoles merge with the cell membrane..
Contractile vacuoles are found in plant cells.
Contractile vacuoles in protists collect water and then expel it when they become full.
No they do not have contractile vacuoles.

The paramecium might have a contractile vacuole, whereas cells like animal and plants just have a normal one.
