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.
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.
Why do marine organisms called osmoregulators?
Marine organisms called osmoregulators are able to maintain a stable internal environment despite the varying salinity of their surroundings. They actively regulate the concentration of solutes and water in their bodies to prevent dehydration or osmotic stress. This adaptation allows them to thrive in saltwater environments where the external osmotic pressure is higher than that of their bodily fluids. Examples of osmoregulators include many fish species and certain invertebrates that utilize specialized cells and organs to manage their internal balance.
Why marine protoctista have no contractile vacoule?
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 are some examples of osmoregulators?
Examples of osmoregulators include marine invertebrates such as crabs and lobsters, as well as freshwater fish like trout and salmon. These organisms actively regulate their internal solute concentrations to maintain osmotic balance with their environment.

Compared to the seawater around them most marine invertebrates are?
Compared to the seawater around them, most marine invertebrates have a higher concentration of ions inside their bodies to maintain osmotic balance. This helps them regulate the movement of water to prevent dehydration. Marine invertebrates have evolved various strategies, such as osmoregulation and excretion, to cope with the different osmotic challenges posed by their environment.

What happen when a marine water protozoan is kept in fresh water?
When a marine water protozoan is placed in fresh water, it experiences osmotic stress due to the difference in solute concentration. Freshwater has a lower concentration of solutes compared to the protozoan's internal environment, leading to water entering the cell through osmosis. This can cause the protozoan to swell and potentially burst, as they are not adapted to cope with such a drastic change in osmotic pressure. To survive, they would need to actively regulate their internal conditions or find a way to return to a saltier environment.

Is there any osmotic difference between a shark's fluids and the sea water in which it swims?
There is no osmotic difference. This happens more with freshwater vertebrates than marine creatures.
What is a example of a marine environment that provides a stable osmotic environment?
An example of a marine environment that provides a stable osmotic environment is the open ocean, particularly the pelagic zone where salt concentrations are consistent due to the vast volume of seawater. This stability allows marine organisms, such as fish and plankton, to maintain their internal osmotic balance efficiently. The deep ocean, with its uniform temperature and salinity, further contributes to this stable environment, enabling adaptations for various marine life forms.
What is osmoconformation?
Osmoconformation is the process by which an organism maintains an internal osmotic balance by conforming to the external osmolarity of its environment. This is typically achieved by regulating the concentration of solutes and water within its body to match that of its surroundings, helping to prevent dehydration or overhydration. Osmoconformers are typically found in marine environments where osmotic pressure can vary significantly.
Why can't marine fishes survive in fresh water?
Because marine fish live in salt water because there found in the ocean.
How do alga perform osmoregulation?
Algae perform osmoregulation primarily through the use of specialized structures called contractile vacuoles, which help expel excess water that enters their cells through osmosis. They also utilize osmotic regulators, such as solutes like glycerol or other organic compounds, to balance internal osmotic pressure with their surrounding environment. In marine algae, the presence of salts helps maintain osmotic balance, while freshwater species may actively uptake ions to counteract the influx of water. Additionally, some algae can adjust their cellular permeability and metabolic processes to adapt to varying osmotic conditions.
