Answer 1

Plants primarily obtain sulfur from the soil in the form of sulfate ions (SO4^2-), which are sulfur substances dissolved in water. Therefore, the correct response is:

as sulfur substances dissolved in water.

Plants absorb these sulfate ions through their root systems, where they are then transported to various parts of the plant for use in synthesizing amino acids, proteins, and other essential molecules.
