explain the role of various mineral elements in plants
Answers
Answer:
Functions of some of the Micronutrients are stated below:
Copper
It is a component of oxidase, cytochrome oxidase, phenolases and ascorbic acid oxidase that is responsible for activating the enzymes.
Copper plays a vital role in photophosphorylation.
It also helps to balance carbohydrate-nitrogen regulation.
Manganese
It is necessary for photosynthesis during the photolysis of water.
The mineral is required for the synthesis of chlorophyll.
It acts as an activator of nitrogen metabolism.
Zinc
It is essential for the synthesis of tryptophan, metabolism of carbohydrates and phosphorus.
It is a constituent of enzymes like alcohol dehydrate-gas, carbonic anhydrase, lactic dehydrogenase, hexokinase, and carboxypeptidase.
Macronutrients
Functions of certain macronutrients are stated below:
Phosphorous
Phosphorous boosts fruit ripening and root growth in a healthy manner by helping translocation of carbohydrates.
They are found abundantly in fruits and seeds.
Deficiency of Phosphorus leads to premature fall of leaves and they turn purplish or dark green in color.
Nitrogen
It is present in various coenzymes, hormones, and ATP etc.
Nitrogen is a vital constituent of vitamins, nucleic acids, proteins and many others.
Deficiency of nitrogen leads to the complete suppression of flowering and fruiting, impaired growth, and development of anthocyanin pigmentation in stems.
Potassium
Potassium is the only monovalent cation that is necessary for plants. It acts as an enzyme activator including DNA polymerase. The deficiency of potassium leads to Mottled chlorosis.
