Why contractile vacuoles would be of little value to one cell organisms living in the ocean?

I do get it,for the organism living in the hypertonic salt water(ocean) the contractile vacuole is most not needed since the water in the organism are already on thier way out!

What type of organisms have cells with very large vacuoles?
A contractile vacuole is a type of vacuole involved in osmoregulation. It pumps excess water out of a cell and is found prominently in freshwater protists. In a Paramecium, a common freshwater protist, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it expels the water through a pore in the cytoplasm which can be opened and closed. This pore has, in some forms of paramecium, disappeared entirely when in use, leading to the idea of a "second cell" in paramecium. Other protists, such as Amoeba, have contractile vacuoles that move to the surface of the cell when full and undergo exocytosis. The contractile vacuole basically stores the extra water, in cells (mostly ciliates) in itself, so if there's a change in environment, a drought for example, the contractile vacuole can release more water into the cell. But if there's a flood, this vacuole will suck a lot of excess water out.
What is the difference between living cells that are organisms and living cells are not organisms?
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
How do living organisms help soil?
Living organisms provide nutrients for the soil.
What is the difference between bacteria and living organisms?
No difference. Bacteria are living organisms.
How do living organisms grow?
Living Organisms grow from cell division and growth hormones
Why contractile vacuoles would be of Little value to one-celled organisms living in the ocean (salt water)?
Contractile vacuoles would be of little value to one-celled organisms living in the salt water because the contractile vacuoles pump out excess water that accumulates in the cell though osmosis. The ocean has salt water so osmosis would not be able to occur.

What is the function of the contractile vacuole in a protozoan?
Living in fresh water, a hypotonic environment, causes water to enter the cell of certain protists (protozoa ) and would lysis the cell unless there were a way to expel this water. This is what contractile vacuoles do. When the fill with enough water microfilament contraction expels the excess water from the vacuole and helps the cell maintain internal isotonicity.
What organell allows free living protists to expel extra water?
The contractile vacuole allows free-living protists to expel extra water
What is the difference between granules and vacuoles?
vacuoles are non living part , fluid filled spaces enclosed by membrane granges also non living but not bounded by any membrane
Are there more living organisms than non living organisms?
There are no non-living organisms, unless you mean dead organisms.
Living organisms come from other living organisms?
All living organisms have to have a host to create other organisms. This includes micro organisms as well as bacterial organisms
What is true for plant and animal cells They each have A mitochondria and chloroplasts B centrioles and cellulose C nuclei and vacuoles D Animal cells are generally smaller than plant cells?
Both are living organisms.
How are living cells that are organisms different from living cells that are not organisms?
All living things are organisms. There is no such thing as a living cell that is not an organism.
What is the difference between living cells that are organisms and living cells are not organisms?
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
Do living organisms come from other living organisms?
Yes, they do.
The structure that keeps a Paramecium living in fresh water from swelling and bursting is called a?
contractile vacuole
