the cells fill with water because of the movement of water by osmosis.

The concentration of water molecules outside the cell is lower than the concentration of the water molecules inside the cell. As a result, water moves out of the cell by osmosis. When water moves out, cells shrink. Put another way, the concentration of solute (salt) is higher outside the cell than inside. More water will flow out of the cell than into the cell through the cell membrane.

Diffusion is the way water moves out of the saltwater fish and into the ocean.Fish and aquatic animals have a complex task of Osmoregulation. Their bodies and especially the gills are bathed in either salt water with high salt levels for sea life, or freshwater with low salt levels for freshwater fish.The saltwater fish tend to keep saltier blood than freshwater fish. In some species, it essentially matches the environment.In the sea, some animals maintain essentially an isotonic solution between the blood and the salt water thus preventing osmosis into the ocean.Other ocean fish drink salt water, and actively pump sodium and chloride ions out of their gills to maintain the osmotic gradient.Freshwater fish have highly efficient kidneys to excrete lots of water and little salt. However, they still must expend energy to pump salt and ions into their bodies.Here is an excellent summary article:http://www2.hawaii.edu/~delbeek/delb11.html

Osmosis in plant cells. (water moves into plant cells by osmosis). Osmosis in animal cells. (water also diffuses in and out of animal cells by osmosis). Hope this answers your question.
The cells take in salt to balance the solute concentration-apex

the cells fill with water
The cells gain water.
The cells fill with water.
Salt controls water absorption so the cells would gain water.
The cells fill with water because of the movement of water by osmosis. (APEX)
Yes, as a fish moves ,from saltwater to freshwater, the concentrations of salt ions drops as freshwater enters the body via osmotic pressure.
The cells will fill with water.
