They provide nutrients for the plants. Also help start photosynthesis.

Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
Where contractile vacuoles are located in amoeba?
contractile vacuoles merge with the cell membrane..
What do contractile vacuoles protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
Why plant cells do not need contractile vacuoles?
Plant cells do not need contractile vacuoles because they have a rigid cell wall that provides structural support and helps maintain internal pressure. The cell wall prevents excessive water uptake, reducing the need for a contractile vacuole to regulate water balance. Plant cells also have large central vacuoles that help store nutrients and maintain turgor pressure.
Why are contractile vacuoles surrounded by mitochondria?
Contractile vacuoles are responsible for regulating osmotic balance in unicellular organisms by expelling excess water. Having mitochondria surrounding the contractile vacuoles helps provide the necessary energy (in the form of ATP) for the vacuoles to pump out water efficiently. This ensures proper functioning of the contractile vacuoles in maintaining cellular homeostasis.
How are contractile vacuoles different then types of vacuoles?
Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
What organelle is found in paramecia cells but not plant cells?
Contractile vacuole is found in paramecia cells but not plant cells. It helps in expelling excess water from the cell to maintain osmotic balance.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
What do vacuoles in protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
Marine protoza do not have contractile vacule?
That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.
How are contractile vacuoles different from types of vacuoles?
Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
Where does a protist that contains contractile vacuoles live?
fresh water
