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.

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.
What is the inner part of the brain that regulates water balance?
The inner part of the brain that regulates water balance is the hypothalamus. It produces hormones like vasopressin (antidiuretic hormone) that help regulate water balance by controlling the amount of water reabsorbed by the kidneys.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
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.
In which organelle does osmosis occur?
Osmosis occurs in the cell membrane of a cell. It is the movement of water across the cell membrane, which controls the balance of water inside and outside of the cell.
Which organ controls water balance and the body temperature and the endocrine system?
The brain controls water balance, body temperature, and the endocrine system.
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.
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.
What is the term dam?
Structure that controls the flow of water.
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.
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.
What cell structure controls the conversion of H2O2 to water?
The peroxisome is the cell structure that controls the conversion of hydrogen peroxide (H2O2) to water and oxygen. It contains the enzyme catalase, which catalyzes the breakdown of H2O2 into water and oxygen.
What system that removes waste from the body and controls water balance is?
The urinary system remove waste from the body and helps maintain water balance. The nervous and endocrine systems regulate and control water balance.
What is a structure that controls water flow called?
tom go
Where protists live?
protists live in water
What portion of the central nervous system is responsible for controlling body temperature water balance and sleep?
The brain controls body temperature, water balance, and sleep.
What is a Portion of the brain that controls the pituitary gland water balance and body temperature called?
hypothalamus
