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.
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 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.
How osmoregulation is carried out in a named protozoan?
Osmoregulation in protozoans like Paramecium is carried out through contractile vacuoles. These organelles collect excess water and expel it from the cell to maintain osmotic balance. The contractile vacuoles help prevent the cell from bursting due to excessive water intake.
Why would you expect a freshwater amoeba to be more likely to ha contractile vacuoles than marine amoeba would?
Marine amoebae live in a saltwater environment. If the vacuoles take in too much salt, it'll suck all the liquidy stuff out of the amoeba itself. Freshwater amoebae are in a freshwater environment so they don't have to worry about that.

What are tokophyra?
Tokophyra are marine dinoflagellates that can produce bioluminescence. They are unicellular organisms found in various marine environments and play a role in the ecosystem as a food source for other marine organisms.

Why would you expect a freshwater amoeba to be more likely to have contractile vacuoles than a marine amoeba?
Because the surrounding freshwater concentration is higher than the salt concentration inside and so all the water from the vacuoles has left because of osomosis. while the marine amoeba has the surrounding salt concentration equal to the concentration inside the vacuole.
Are lion fish unicellular?
No, lionfish are not unicellular; they are multicellular organisms. Lionfish belong to the family Scorpaenidae and are classified as marine fish. They have complex body structures, including specialized organs and systems, which are characteristic of multicellular animals.
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.
Is anemone a unicellular organisms?
No, anemones are not unicellular organisms; they are multicellular marine animals belonging to the phylum Cnidaria. Anemones have a complex structure, including a cylindrical body, tentacles, and specialized cells called cnidocytes that contain stinging structures. They are commonly found in ocean environments, often attached to rocks or coral reefs.
What applies to most protists?
Protists are typically unicellular organisms with a diverse range of characteristics and behaviors. They can be found in a variety of environments, including freshwater, marine, and terrestrial habitats. Many protists are important in the food chain as primary producers or as consumers.
What kind of living organisms are classified under algae?
Algae are a diverse group of photosynthetic organisms that can be unicellular or multicellular. They include seaweeds, pond scum, and phytoplankton. Algae can be found in various habitats, from freshwater to marine environments.
