Hint: All organisms following different types of process in their development or growth. For a plant as well as an animal for the growth or development some nutrition is required that means some water with essential elements. These elements are helpful so much of the unconditional growth of the plant.
Complete answer:
Macronutrients: They are generally required in plant tissues in large amounts i.e. excess of 10m mole Kg of dry matter. They are nine in a number: carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur, potassium, calcium, magnesium.
Out of this carbon, hydrogen and oxygen are mainly obtained from CO, and water molecules while the others can be absorbed from the soil as mineral nutrition.
Micronutrients or trace elements: They are needed in very small amounts i.e. less than 10m mole Kg of dry matter. They are eight in number These include iron, manganese copper, molybdenum. zinc, boron, chlorine and nickel. Fe is required in large amounts in comparison to other micronutrients, while Mo is required in minimum quantity. In addition to the 17 essential elements, there are some beneficial elements such as sodium (A triplex), silicon (grasses), cobalt (legumes) and selenium (Astragals). They are required by higher plants.
Essential elements can also be grouped into four broad categories based on their diverse functions and characterization are,
These categories are given below respectively:
> Essential elements that are components of biomolecules and hence structural elements of cells.
Examples: carbon, hydrogen, oxygen and nitrogen.
> Essential elements that are components of energy-producing chemical compounds in plants generally
E.g.: Magnesium in chlorophyll as well as phosphorus in ATPi.e.
> Essential elements that activate enzymes, for example, Mg2 is an activator for both RuBisCO and
PEP case, both of which are critical enzymes in photosynthetic carbon fixation: Zn2 is an activator
alcohol dehydrogenase and Mo nitrogenase during nitrogen metabolism.
Some essential elements can alter the osmotic potential of a cell. Potassium plays an important role in the opening and closing of stomata.
So, C is the correct answer.
Note:
We should know that potassium, sulphur, calcium, phosphate are the main components to perform plant growth or development also. So these are the all major minerals who play a major role in controlling the growth and development of a green plant. All the minerals generally found in the soil.
