Protists use contractile vacuoles to regulate water and maintain osmotic balance. These vacuoles collect excess water that enters the cell and expel it through a process of contraction. This mechanism is especially important for freshwater protists, which are constantly gaining water due to the lower concentration of solutes in their environment compared to their cytoplasm. By effectively managing water levels, protists can prevent cell lysis and maintain homeostasis.
What else can I help you with?
How do protists maintain water balance?
Protists maintain water balance through osmoregulation, which involves controlling the movement of water and ions across their cell membranes. They use contractile vacuoles to regulate water content by expelling excess water that enters the cell through osmosis. Additionally, some protists have adapted to specific environments by evolving structures or behaviors that help them avoid dehydration or over-hydration.
Does a Protists a have cells without nuclei?
No, protists have a nucleus which makes them procaryotic
What protists use spores to reproduce?
Some protists that use spores to reproduce include slime molds, water molds, and various types of algae. Spores are typically formed as a means of survival under unfavorable conditions, allowing these protists to spread and germinate when conditions become more suitable.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
What do some protists like algae use sunlight water and CO2 to get energy through?
I think you are asking about photosynthesis.

How do protists use excretion?
Protists excrete waste products such as carbon dioxide, ammonia, and other metabolic byproducts from their cells. This helps maintain internal balance and prevents the accumulation of toxic substances. Excretion also allows protists to regulate osmotic balance by expelling excess water and ions.
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.
Which structure is used most directly by all protist for the process of excretion?
All protists use contractile vacuoles for the process of excretion. These organelles help regulate water balance by expelling excess water and waste products from the cell.
Does a Protists a have cells without nuclei?
No, protists have a nucleus which makes them procaryotic
Where protists live?
protists live in water
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
What protists use spores to reproduce?
Some protists that use spores to reproduce include slime molds, water molds, and various types of algae. Spores are typically formed as a means of survival under unfavorable conditions, allowing these protists to spread and germinate when conditions become more suitable.
Do protists make energy?
Yes, protists can make energy through a process called photosynthesis, in which they use sunlight to convert carbon dioxide and water into glucose. Additionally, some protists can obtain energy by consuming organic matter as heterotrophs.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
