Which of the following is true?

water is important to some organisms.
some substances must be dissolved in water before they can be used.
all organisms obtain water through food.
plant cells are unaffected when water is scarce.

The most appropriate answer would be "Some substances must be dissolved in water before they can be used".  

Water is one of the most essential substances for all organisms. It helps in performing all the major functions of the living system such as digestion, excretion, transportation et cetera.

Water is considered as a universal solvent as it can dissolve a maximum number of substances as compared to any other solvent.

It is the reason that it is used as a solvent to dissolve substances which can not be used in their raw form.

For example, NaCl is administered in hospitals in the form of saline.
