Question 11
A plant's roots are growing poorly and red and purple spots are appearing on its leaves. Which mineral salt is short?
The right answer is the one marked above.
Phosphorus. In plants it works as a component of nucleic acid and of ATP.
Each shortage writes a different signature on the plant. Potassium: chlorosis, with the leaves going yellow or brown, because potassium runs protein synthesis and the opening and closing of the stomata.
