- Isolating materials that might be harmful or a threat to the cell
- Containing waste products
- Containing water in plant cells
- Maintaining internal hydrostatic pressure or turgor within the cell
- Maintaining an acidic internal pH
- Containing small molecules
- Exporting unwanted substances from the cell
- Allows plants to support structures such as leaves and flowers due to the pressure of the central vacuole
- In seeds, stored proteins needed for germination are kept in 'protein bodies', which are modified vacuoles.

Which protists are contractile vacuoles easy to see?
Contractile vacuoles are commonly found in freshwater protists, such as amoebas and paramecia. These organisms live in hypotonic environments and use contractile vacuoles to regulate their water balance by expelling excess water to prevent bursting.
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.
What are the three types of protists?
The three types of protists are protozoa (animal-like protists), algae (plant-like protists), and slime molds (fungus-like protists). Each type has unique characteristics and can be found in various environments.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
What types of eukaryotic cells have vacuoles that act like lynsosomes?
Vacuoles are found in plant and fungal cells because sometimes the vacuoles act like lysosomes. A vacuole is a vesicle. They contain enzymes that help a cell digest particles. The large central vacuole in plant cells stores water and other liquids. Large vacuoles full of water help support the cell. Some plants wilt when their vacuoles lose water.
What do vacuoles in protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.

Briefly state the functions what vacuoles?
In protists, vacuoles have the additional function of storing food which has been absorbed by the organism and assisting in the digestive and waste management.

The large central vacuole in plant cells stores water and other liquids. Large vacuoles full of water help support the cell. Some plants wilt when their vacuoles lose water.
Are vacuoles membrane bound?
Yes, vacuoles are membrane-bound organelles found in the cells of plants and some protists. They are surrounded by a membrane, known as the tonoplast, that separates the contents of the vacuole from the cytoplasm of the cell. Vacuoles play various roles in the cell, such as storing nutrients, maintaining turgor pressure, and regulating cell expansion.
What is not found in vacuoles?
Nucleus and mitochondria are not found in vacuoles. Vacuoles primarily consist of water, enzymes, nutrients, and waste materials.
What are the 4 different types of protists?
The 4 different types of protists are to get away from bacteria,
Are archaebacteria and eubacteria both protists?
No, archaebacteria and eubacteria are not considered protists. They are both types of bacteria that are classified in different domains (Archaea and Bacteria), separate from the domain Eukarya where protists are found.
