Which of the following is the correct set of micronutrients for plants?
A. Mg, Si, Fe, Cu, Ca
B. Cu, Fe, Zn, B, Mn
C. Mg, Fe, Zn, B, Mn
D. Mo, Zn, Cl, Mg, Ca

Explanation

Solution

The crucial elements required by the plant are broadly categorized into two categories: micronutrients and macronutrients. The nutrients that are required in smaller quantities by the plant are known micronutrients and the nutrients that are required in large quantities by the plant are known macronutrients.

Complete step by step answer: Micronutrients includes seven essential elements which includes the following: boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and chlorine (Cl). The chemical elements that are required in small quantities are known as micronutrients. These nutrients are vital for the appropriate growth and development, and proper physiology of the plant. They are also necessary for plant metabolism and the external supply of the nutrients. In the absence of these nutrients, the plant is not able to complete a regular life cycle. Micronutrients perform various functions including, plant metabolism, nutrient regulation, reproductive growth, and chlorophyll synthesis. They are also involved in the production of carbohydrates, development of fruit and seed.
Among the given options, Copper (Cu), Iron (Fe), Manganese (Mn), Zinc (Zn), and Boron (B) all are the example of micronutrients.
So, the correct answer is option B.

Additional information: The nutrients that are required in large quantities by the plant are known macronutrients. Almost half of the essential elements are regarded as macronutrients. These include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur.

Note: The essential elements required by the plants are present below the soil in the form of salts. The plants absorb these elements as ions. Macronutrients are absorbed in large quantities. Hydrogen, oxygen, nitrogen and carbon contribute about 95% of the dry weight of the biomass of the plant. The micronutrients are required by the plant tissue in small quantities which are measured in parts per million that range from 0.1 ppm to 200 ppm, or less than 0.02% of the dry weight.
