- $ Ca^{2+} $
- $ Mg^{2+} $
- $ K^{+} $
- Sulphur
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Deficiency of potassium results in marginal and intervenal mottled chlorosis and necrosis. It is required for synthesis of protein, cell membrane osmotic potential, turgidity of cell etc.

Essential Mineral Elements
Mineral Elements:
A large number of inorganic elements are necessary for all the life processes and hence should be taken into our diets in adequate amounts. Any deficiency in these minerals leads to an abnormality in the metabolic functioning of the body.
Essential Mineral Elements in Plants
There are two types of minerals that are essential for plant growth, such as:
1. Macrominerals
Minerals like Phosphorous, carbon, silicon, magnesium, hydrogen, sodium, nitrogen, potassium, calcium, oxygen, selenium, and sulfur are required in abundance for proper plant growth and are also found abundantly in plant tissues. Hence, they are known as macrominerals.
2. Microminerals
A few minerals like Iron, boron, zinc, cobalt, chlorine, nickel, manganese, copper, molybdenum, etc. are required in lesser quantities for proper growth by the plants and therefore, they are called microminerals. Further they are also called trace elements.
