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.
What do protists use to regulate water?
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 organelle allows free living protists to expel etra water?
The organelle that allows free-living protists to expel excess water is called the contractile vacuole. This structure collects excess water that enters the protist's body and then contracts to expel it, helping to maintain osmotic balance and prevent the cell from bursting in hypotonic environments. Contractile vacuoles are particularly important in freshwater protists, where water influx is constant.
What cell structure prevents lysis in many single celled protists living in a fresh water environment?
Contractile vacuole helps to prevent lysis in many single-celled protists by regulating the water content within the cell. It accumulates excess water and then expels it from the cell, helping to maintain the cell's osmotic balance in a fresh water environment.
What dos the contractile vacuole do?
It eliminates excess water from the cytoplasm of freshwater protists.
How is water maintained?
Water is maintained in the body through filtration. The kidneys help to maintain the water balance of different urine concentrations.
The water balance of the body is maintained bu negative feedback what does this mean?
Water balance refers to the amount of water gained and lost by the body.
What structure controls the water balance in protists?
Contractile vacuoles control the water balance in protists by actively pumping out excess water to prevent them from bursting due to osmotic pressure. These vacuoles accumulate water through specialized channels and release it to the outside through an opening in the cell membrane.
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.
Is it true or false that electrolyte balance during exercise can be maintained by drinking water in combination with a balance diet?
yes
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.

Where protists live?
protists live in water

Contractile vacuoles are particularly important in freshwater protists, where water influx is constant.
What is the function of the contractile vacuole?
The contractile vacuole functions as a water regulatory organelle in freshwater protists by collecting excess water and expelling it from the cell. Its primary role is to maintain the cell's internal environment by preventing it from swelling and potentially bursting due to excess water intake.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
