The mechanism of life would be entirely different.
What will happen if water gets inside gas tank
In plants, large spaces inside cells called vacuoles can hold water. In animal cells, the cell membrane contains water transporters or water channels that help in removind water if there is too much water inside cells
Water is in fact not made of cells. Water however is a major compound found inside of nearly all cells.
water, water everywhere
Gains water
because most of the chemical reactions that happen in your metabolism happen in water.
you have made a water balloon!
Water potential of the water inside the cells is higher that the water potential of the water outside the cells. (That would means the concentration of "pure" water inside the cells are higher than that outside the cells) Water moves from an higher water potential to an lower water potential. Thus Plasmolysis of the cells will take place. Which means the Nucleus,Vacuole and all the other cellular material will move from the inside of the cell to the outside.
In a hyptonic solution, water will move into the cells of the egg, and it will swell, and the cells will burst.
inside the chloroplast in the plants cells.
It depends of your conditions and the quantity you drink. If you feel a little thirsty it means the water contents in your cells is a little low so when you drink water enter into the cells, the salile concentration reaches the required level and thirst banishes. On the other side if you are extremely dehydrated as could happen very fast if you get lost in a very hot and dry place, the water content inside your cells becomes very low and drinking will just save your life. On the other, rather theoretical extreme, drinking lots of water (around 20 liter, if memory serves me well) would kill you by depleting the potassium content inside your cells. As you can see all effects depend on water which is the main component of most beverages. You would get the same effects using pure water instead of soda.
In the salt solution the concentration of water inside the cells of the potato is higher than that outside. Therefore water molecules move from inside the potato where there is higher concentration of water molecules to outside the potato where there is a lower concentration of water molecules through semipermeable membrane of the potato cells. This process is called osmosis.
