Is a vacuole eukaryotic or prokaryotic?

Internal membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, vacuoles, and lysosomes are present….Prokaryotes vs. Eukaryotes CellEdit.

Are contractile vacuoles found in prokaryotes?

A contractile vacuole (CV) is a sub-cellular structure (organelle) involved in osmoregulation. It is found predominantly in protists and in unicellular algae.

Do eukaryotic cells have a contractile vacuole?

A contractile vacuole is a specialized type of vacuole in eukaryotic cells, particularly protozoa and certain unicellular algae. It is involved in osmoregulation.

What is the role of contractile vacuole in prokaryotes?

The contractile vacuole (CV) complex is an osmoregulatory organelle of free-living amoebae and protozoa, which controls the intracellular water balance by accumulating and expelling excess water out of the cell, allowing cells to survive under hypotonic stress as in pond water.

What cells have vacuoles?

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

Is Golgi prokaryotic or eukaryotic?

Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes. Animals, plants, fungi, and protists are all eukaryotes.

What cells have contractile vacuoles?

Contractile vacuole, regulatory organelle, usually spherical, found in freshwater protozoa and lower metazoans, such as sponges and hydras, that collects excess fluid from the protoplasm and periodically empties it into the surrounding medium. It may also excrete nitrogenous wastes.

What cell is vacuole found in?

What is the main function of contractile vacuole in protozoa?

The function of contractile vacuole is osmoregulatory. Water in freshwater protozoa enters the organism by endosmosis and during feeding. If the organism does not possess a mechanism to get rid of this excess water, it will swell to the point of rupture and dissolution.

How do you identify a contractile vacuole?

What is the main function of contractile vacuole in protozoans?

Which of the following is the main function of contractile vacuole?

A contractile vacuole (CV) is an organelle, or sub-cellular structure, that is involved in osmoregulation and waste removal. Thus, the CV acts as a protective mechanism against cellular expansion (and possibly explosion) from too much water; it expels excess water from the cell by contracting.
