Amoeba only have one.Further reading: http://en.wikipedia.org/wiki/Contractile_vacuole
contractile vacuoles merge with the cell membrane..
Food is stored in food vacuoles within an amoeba. When an amoeba engulfs food particles through phagocytosis, the food vacuole forms around the ingested material. Enzymes then break down the food inside the vacuole for digestion.
Marine amoebae live in a saltwater environment. If the vacuoles take in too much salt, it'll suck all the liquidy stuff out of the amoeba itself. Freshwater amoebae are in a freshwater environment so they don't have to worry about that.
The paramecium might have a contractile vacuole, whereas cells like animal and plants just have a normal one.
Yes, many species of amoeba have a contractile vacuole that helps regulate water content within the cell by expelling excess water to prevent bursting due to osmotic pressure.

Digestion in amoeba occurs in the food vacuoles, which are formed when the cell engulfs food particles through phagocytosis. The food vacuoles contain digestive enzymes that break down the food into smaller molecules, which are then absorbed by the cell for nourishment.

Plant cells, amoeba, and paramecium all have cell membranes, vacuoles, and a nucleus. A plant cell has cytoplasm, while amoeba and paramecium have endoplasm and ectoplasm.
Structures such as the Golgi apparatus, mitochondria, and vacuoles that are present in amoeba and paramecium are also found in plant cells. Additionally, both plant cells and these protists contain a cell membrane, cytoplasm, and a nucleus.
They have an excretory function.They remove excess water from cells.
Because the surrounding freshwater concentration is higher than the salt concentration inside and so all the water from the vacuoles has left because of osomosis. while the marine amoeba has the surrounding salt concentration equal to the concentration inside the vacuole.
Vacuoles. Vacuoles store food and waste. Some vacuoles store extra water. They are often described as liquid filled space and are surrounded by a membrane. Some cells, most notably Amoeba, have contractile vacuoles, which can pump water out of the cell if there is too much water.
