Sulfur is part of the amino acids cystein and methionin, plants take up sulfur in the form of $H_2S$. These organisms will also need a way to get rid of excess sulfur, how? In what compounds?
Judging by the smell of some farts, I guess $H_2SO_4$ plays a role, but I can't imagine that one get'S rid of all the sulfur this way.

Plants do not take up H$_2$S, this is limited to a few microorganisms. Plants take up soluble forms of sulphur as sulphates, and the surely do not build up sulfuric acid (which would destroy the cells).
