A contractile vacuole is a type of vacuole involved in osmoregulation. It pumps excess water out of a cell and is found prominently in freshwater protists. In a Paramecium, a common freshwater protist, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it expels the water through a pore in the cytoplasm which can be opened and closed. This pore has, in some forms of paramecium, disappeared entirely when in use, leading to the idea of a "second cell" in paramecium. Other protists, such as Amoeba, have contractile vacuoles that move to the surface of the cell when full and undergo exocytosis. The contractile vacuole basically stores the extra water, in cells (mostly ciliates) in itself, so if there's a change in environment, a drought for example, the contractile vacuole can release more water into the cell. But if there's a flood, this vacuole will suck a lot of excess water out.

∙ 6y agoYes animals do have vacuoles in their cells. animals are made up of cells and animal cells have vacuoles just like plant cells, but unlike plant cells, the vacuoles are not permanent.

What type of cell doesn't have a nucleus?
Prokaryotic organisms don't have a nucleus. And also bacteria do not have a nucleus they only have vacuoles as they are thread like material. All of the prokaryotic and archea cells don't have a nucleus. Only eukaryotic cells have a nucleus.
How many vacuoles does an animal cell contain?
There is no set number of vacuoles in animal cells. There can be very few or very many depending on the type of cell. Plant cells usually have one very, very large central vacuole that fills with water to keep the plant upright, but there is no analogous structure in animal cells.
Structure that stores food molecules?
It depends on the type of cell. In animal cells, food is stored in vacuoles; in plant cells, glucose is made during photosynthesis in the chloroplast, the glucose may be stored in the Large Central Vacuole or may be directly converted into Adenosine Triphosphate in the mitochondria.
Which type of cells did multicellular organisms arise?
Eukaryotic cells
Why do animal cells have small vacuoles whole plant cells have large vacuoles?
Plant cells have a large vacuole due to the amount of water the cell must hold to maintain its shape. The water in the vacuole creates something called turgor pressure. When the vacuole has lots of water, the turgor is high and pushes against the cell wall so the cell is rigid. When vacuole has little water, the turgor is low so the cell is flaccid. Animal cells don't have to worry so much since our cells are already in an aqueous environment and get water in lots of other ways.
What type of cell contain large vacuoles?
plant cells
What type of cells have a large central vacuole?
Most mature plant cells have a large, central vacuole; other than that, most cells contain only small vacuoles. In plants, immature cells, such as developing cells in the meristem, do not have large, central vacuoles. Also, the vacuoles in cells of the vascular cambium fluctuate in both size and number, depending on the season.
What type of cell in your bodies would have a very large amount of vacuoles?
animal cells
What type of cells contain vacuoles?
plant cells
What type of membrane surrounds vacuoles in plants cells?
tonoplast

What is the vacuoles job in the animal cell?
The vacuole is type of trash bin in animal cells.
What is the purpose of a vacoule?
Vacuoles are found in most animal cells and all plant cells. Vacuoles have various functions according to the type of cell, but generally the main function of a vacuole is to store water and waste products.
