Question

List out the elements of a chemical plant and give descriptions of each of their functions.

Answer 1

Nitrogen, phosphorus, and potassium are Primarynutrients. As well  they are need in maximum quantity by plants as fertilizer.

NITROGEN

· it is need for formation of amino acids and it is Essential for plant cell division, vital for plant growth.
· Involving in photosynthesis and it is Necessary component of vitamins
· Helps in production and use of carbohydrates
· Affects energy reactions in the plant

PHOSPHORUS

· Involving in photosynthesis, respiration, energy storage and transfer, cell division, and enlargement
· Promotes early root formation and growth
· Improves quality of fruits, vegetables, and grains
· Vital to seed formation
· Aids plants survive harsh winter conditions
· Increases water-use efficiency
· Hastens maturity

POTASSIUM

  
· Need for Carbohydrate metabolism and the break down and translocation of starches
· Increases photosynthesis and water-use efficiency
· Necessary for protein synthesis
· Important in fruit formation
· It activates enzymes and controls their reaction rates
· Improves quality of seeds and fruit and winter hardiness
· Increases disease resistance

calcium, magnesium, and sulphur are secondary nutrients  which are needed in lesser amounts than the primary nutrients.

CALCIUM

  · Used for Continuous cell division and formation
· Involving in nitrogen metabolism
· Decreases plant respiration & Increases fruit set
· Aids translocation of photosynthesis from leaves to fruiting organs
· Essential for nut development in peanuts
· Stimulates microbial activity

MAGNESIUM

  · Important element of chlorophyll production
· Improves utilization and mobility of phosphorus
· Activator and component of many plant enzymes
· Directly related to grass tetany
· Increases iron utilization in plants & · Influences earliness and uniformity of maturity

SULPHUR

  · Presents in amino acids
· Helps develop enzymes and vitamins
· Promotes nodule formation on legumes
· Aids in seed production
· Need in chlorophyll formation

boron, chlorine, cooper, iron, manganese, molybdenum, and zinc are called  micronutrients which are used in very small amounts.

BORON

· Essential of germination of pollon grains and growth of pollen tubes & seed and cell wall formation
· Promotes maturity
· Need for sugar translocation
· Affects nitrogen and carbohydrate

CHLORINE

· Interferes with P uptake
· Enhances maturity of small grains on some soils

COPPER

· Catalyzes several plant processes
· Major function in photosynthesis & reproductive stages
· Indirect role in chlorophyll production
· Increases sugar content
· Intensifies color
· Improves flavor of fruits and vegetables

IRON

· Promotes formation of chlorophyll
· Acts as an oxygen carrier
· Iron reactions involving cell division and growth

MAGANESE

· Functions as a part of certain enzyme systems
· Helps in chlorophyll synthesis
· Increases the availability of P and Calcium

MOLYBDENUM

· Required to form the enzyme "nitrate reductas" which reduces nitrates to ammonium in plant
· Helps in the formation of legume nodules
· Necessary to convert inorganic phosphates to organic forms in the plant

ZINC

· Helpss plant growth hormones and enzyme system
· Necessary for chlorophyll production, carbohydrate formation &  starch formation   
· Aids in seed formation
