Which organelle is present in a paramecium protozoa but absent in the cells of a strawberry plant?
A contractile vacuole is present in a paramecium protozoa but absent in the cells of a strawberry plant. The contractile vacuole helps regulate water content in paramecium cells by expelling excess water, a function not needed in plant cells due to their rigid cell walls.
Why is a contractile vacuole essential to the survival of the amoebae and the paramecium?
A contractile vacuole helps amoebae and paramecium regulate the water content within their cells by periodically expelling excess water to prevent them from bursting due to osmotic pressure. Without a contractile vacuole, these organisms would be vulnerable to cellular damage from fluctuations in hydration levels and could potentially die from osmotic stress.
What removes excess water in a paramecium?
A contractile vacuole in a paramecium removes excess water by collecting and expelling it from the cell. This process helps regulate the osmotic pressure within the cell to prevent it from bursting due to excess water intake.
Does an amoeba have more than one contractile vacuole?
No, an amoeba typically has one contractile vacuole, which is responsible for expelling excess water and waste from the cell. The contractile vacuole helps to regulate the osmotic balance of the cell by maintaining the proper water content.
What would happen to the paramecium if it did not have a contractile vacuole?
The paramecium would have difficulty regulating its water balance, leading to swelling and potential bursting from an influx of water. Without a contractile vacuole, the paramecium would struggle to expel excess water and maintain osmotic balance, ultimately leading to cell damage or death.
What structure pumps out excessive water and waste in paramecium?
contractile vacuole
Network of ducts and reservoirs that allow paramecium to equalize water pressure through the cell membrane?
The contractile vacuole system functions as a network of ducts and reservoirs within a paramecium to regulate water balance and remove excess water from the cell. The system helps the paramecium maintain osmotic equilibrium by actively pumping out water that enters the cell through osmosis, preventing it from bursting due to excessive water intake. This allows the paramecium to survive in various aquatic environments with fluctuating osmotic conditions.
What structure expels excess water in the amoeba?
The contractile vacuole is the structure in amoeba responsible for expelling excess water and maintaining osmotic balance within the cell. It collects and removes the excess water by contracting and expelling it out of the cell.
What is function of contractile vacuole in amoeba?
The contractile vacuole in amoeba functions to regulate the water content within the cell by collecting and expelling excess water to prevent the cell from bursting. It helps maintain the proper balance of water and ions in the cell to ensure its survival in different environments.
How does a contractile vacuole in a paramecium help maintain homeostasis?
it pumps water into the cells
What would happen to the paramecium if the water-expelling vesicle stopped working?
The paramecium would eventually die because the paramecium wouldn't get any water and without the water-expelling vesicle the paramecium can't get the water out without getting other bacterias while doing so.
What are the functions of the water - expelling vesicle?
