What is a contractile vacuole and what types organisms have them?

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 is the difference between a vacuole and a central vacuole?

A vacuole is a sphere filled with fluid and molecules inside a cell. The central vacuole stores water and maintains turgor pressure in a plant cell. ... Vacuoles are also found in animal, protist, fungal, and bacterial cells, but large central vacuoles are only found in plant cells.

What are the two types of vacuoles?

Vacuoles are of 4 types: Food vacuole, Sap vacuole, Gas vacuole, Contractile vacuole.

What are vacuoles name the type of vacuole that occurs in amoeba?

In Amoeba contractile vacuoles collect excretory waste, such as ammonia, from the intracellular fluid by both diffusion and active transport.

What type of vacuoles are present in animal cells?

in plant cell large vacuoles are found whereas in animal cell samll or no vacuoles are found. hope my answer helped you.

What is the difference between contractile vacuole and food vacuole?

Food Vacuole vs Contractile Vacuole

Food vacuoles are membranous structures that participate in the process of digestion. Contractile vacuoles are membranous structures which participate in osmoregulation of the cell and prevent the bursting of cells.

What is the function of the contractile vacuole found in protists?

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 is the function of a contractile vacuole Why do some protists need these?

The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.

How are plant vacuoles different from animal vacuoles?

Vacuoles in both plant and animal cells serve as storage organelles inside the cell. The main difference between plant and animal vacuoles is that plant vacuoles are large in size and are single in number whereas animal vacuoles are small in size and are more in number. ... Animal vacuoles store nutrients, ions, and water.

How are plant vacuoles different from animal and human vacuoles?

Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present. Large vacuoles help provide shape and allow the plant to store water and food for future use. The storage function plays a lesser role in animal cells, therefore the vacuoles are smaller.

How are the vacuoles of plant cells different from the vacuoles of animal cells?

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.

Which type of vacuoles provide buoyancy to bacteria?

Gas vacuoles are aggregates of hollow cylindrical structures called gas vesicles. They are located inside some bacteria . A membrane that is permeable to gas bound each gas vesicle. The inflation and deflation of the vesicles provides buoyancy, allowing the bacterium to float at a desired depth in the water.

What are vacuoles Class 9?

They are storage sacs for solid or liquid content.In animals cell,they are small and temporary. They store water,glycogen and proteins,single membrane maintain water balance.
