Classification of plant mineral nutrients according to biochemical function

Mineral nutrient	Functions
A.)  Silicon(Si)	1.)    Constituent of alcohol dehydrogenase, glutamic dehydrogenase, carbonic anhydrase, etc
B.)  Manganese(Mn)	2.)    Component of sugar phosphates, nucleic acids, nucleotides, coenzymes, phospholipids, phytic acid, etc. Has a key role in reactions that involve ATP
C.)  Zinc(Zn)	3.)    Contributes to cell wall mechanical properties, including rigidity and elasticity.
D.)  Phosphorous(P)	4.)    Component of ascorbic acid oxidase, tyrosinase, monoamine oxidase, uricase, cytochrome oxidase, phenolase, laccase, and plastocyanin.
E.)   Copper(Cu)	5.)    Required for activity of some dehydrogenases, decarboxylases, kinases, oxidases, and peroxidases. Involved with other cation-activated enzymes and photosynthetic O2 evolution

In very dry soils, the water potential (Yw) may fall below what is called the permanent wilting point, the water potential of the soil is so low that plants cannot regain turgor pressure even if all water loss through transpiration ceases. This means that

a) The hydraulic conductivity decreases drastically 

b) The water potential of the soil (Yw) is less than or equal to the osmotic potential (Ys ) of the plant

c) The water potential of the soil (Yw) is more than the osmotic potential (Ys) of the plant

d) cell osmotic potential (Ys) varies with plant species, the permanent wilting point is clearly not a unique property of the soil, it depends on the plant species
