Marine protoctista typically lack contractile vacuoles because they inhabit environments where the osmotic pressure is balanced, such as seawater. In these conditions, the intake of water through osmosis is minimal, reducing the need for a structure to expel excess water. Instead, these organisms have adapted to regulate their internal environment through other cellular mechanisms. Consequently, the absence of a contractile vacuole is an evolutionary response to their saline habitat.
What else can I help you with?
What organelle helps remove excess water?
The vacuole is the organelle responsible for removing excess water from the cell. It acts as a storage unit for water and other substances, allowing the cell to maintain proper water balance. When there is excess water, the vacuole will absorb it to prevent the cell from bursting.
Marine protoza do not have contractile vacule?
That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.
What is contractile vacuole in amoeba related with?
The contractile vacuole in amoeba is related to osmoregulation, which is the process of regulating the water and ion balance within the cell. It helps to expel excess water and waste products to prevent the cell from swelling or bursting.
Marine protozoa do not have contractile vacuole why?
Marine protozoa may not have a contractile vacuole because they are adapted to live in a consistently isotonic environment, with the same salt concentration inside and outside their cells. Thus, they do not need a contractile vacuole to regulate water balance since there is no constant need to expel excess water.
Contractile vacuole are not found in marine water forms why?
Marine water has a higher concentration of salt compared to fresh water, which creates a more stable osmotic environment for marine organisms. As a result, marine organisms do not need contractile vacuoles to regulate water balance and remove excess water, as they do not face the same risk of swelling and bursting due to osmotic pressure.

Organelle that pumps water out of the cell?
The Contractile Vacoule.
How excretion take place in protozoa?
excreation takes place by contractile vacoule

A paramecium eliminates excess water by means of?
A paramecium eliminates excess water through a contractile vacuole, a specialized structure that collects and expels water to regulate the cell's internal environment. The contractile vacuole helps maintain osmotic balance by preventing the cell from taking in too much water and potentially bursting.

Do the animal cells have a vacoule?
Yes animal do have vacoule cells
Why don't marine unicellular organisms have contractile vacuoles?
Marine unicellular organisms typically have stable osmolarity in their surrounding environment, reducing the need for contractile vacuoles to regulate water balance. Additionally, many marine organisms have evolved other mechanisms to regulate osmotic balance, such as ion transport mechanisms.
If a paramecium were to swim from a hypotonic environment to an isotonic one would the activity of its contractile vacuole increase or decrease?
The activity of the contractile vacoule would decrease. While in the hypotonic solution, water was moving into the paramecium because it had a higher solute concentration that the solution that it was in and water follows solute. So, the isotonic solution would contain the same solute concentration as the paramecium so there would be no net water movement. Therefore, the contractile vacoule would decrease in its activity because there would be no water entering or exiting the paramecium.
Do animal cells have a vacoule?
any kind of animal cell have a vacoule duhhh!!
