The contractile vacuole has several structures attached to it in most cells, such as membrane folds, tubules, water tracts and small vesicles. These structures have been termed the spongiome; the contractile vacuole together with the spongiome is sometimes called the "contractile vacuole complex" (CVC). The spongiome serves several functions in ...
The contractile vacuole complex works periodically contracts to remove excess water and ions from the cell to balance water flow into the cell. [26] When the contractile vacuole is slowly taking water in, the contractile vacuole enlarges, this is called diastole and when it reaches its threshold, the central vacuole contracts then contracts ...
The cytostome is located on the anterior end of the cell close to a structure known as the flagellar pocket. The flagellar pocket is also an invagination in the cell and also serves as a site of endocytosis. The opening of the cytostome is approximately level with the opening of the flagellar pocket. [3] Ciliophora is a phylum of protozoa. The ...

Anything left in the food vacuole by the time it reaches the cytoproct is discharged by exocytosis. Most ciliates also have one or more prominent contractile vacuoles , which collect water and expel it from the cell to maintain osmotic pressure , or in some function to maintain ionic balance.
A single contractile vacuole is positioned at the posterior end of the organism, attached to a collecting canal that extends towards the anterior end. When filled with fluid, the vacuole takes up a substantial portion of the posterior end. The distinction between the contractile vacuole and the rest of the cytoplasm is usually very clear. [6 ...
No app can fix your focus. Here’s how CNN’s Upasna Gautam ditched the productivity hacks and embraced the basics to get the most out of life.
Vacuoles are cellular organelles that contain mostly water. [citation needed] Plant cells have a large central vacuole in the center of the cell that is used for osmotic control and nutrient storage. Contractile vacuoles are found in certain protists, especially those in Phylum Ciliophora.
