About fifty years ago plant physiol

About fifty years ago plant physiologists set out to grow roots by themselves in solutions in laboratory flasks.The scientists found that the nutrition of isolated roots was quite simple.They required sugar and usual minerals and vitamins. However, they did not require organic nitrogen compounds.These roots got along fine on mineral inorganic nitrogen. Roots are capable of making their own proteins and other organic compounds.These activities by roots require energy,of course.The process of respiration uses sugar to make the high energy compound ATP,which drives the biochemical reactions. Respiration also requires oxygen.Highly active roots require a good deal of oxygen.
The study of isolated roots has provided an understanding of the relationship between shoots and roots in intact plants.The leaves of the shoots provide the roots with sugar and vitamins,and the roots provide the shoots with water and minerals.In addition,roots can provide the shoots with organic nitrogen compounds.This comes in handy for the growth of buds in the early spring when leaves are not yet functioning.Once leaves begin photosyn-thesizing,they produce protein,but only mature leaves can “export” protein to the rest of the plant in the form of amino acids.

About fifty years ago set out to grow plant physiologists roots by Themselves print print solutions flasks.The laboratory scientists of nutrition found rằng isolated roots of sugar and was quite simple.They required minerals and vitamins usual. Tuy nhiên, did not require organic nitrogen chúng compounds.These got along fine roots on inorganic mineral nitrogen. Roots are capable of making proteins and other organic Their Own Activities compounds.These by roots require energy, of course.The process of respiration dùng to make the high sugar energy compound ATP, the biochemical Reactions mà drives. Respiration oxygen.Highly am also requires a good deal require the active roots of oxygen.
The study of isolated roots has an understanding of the relationship given below the between shoots and roots print plants.The Intact leaves of the shoots cung the roots with sugar and vitamins, and the cung roots the shoots with water and minerals.In addition, shoots with roots can cung the organic nitrogen comes in handy compounds.This for the Growth of buds in the early spring leaves are not yet functioning.Once khi leaves begin photosyn-thesizing, chúng tạo protein, but only mature leaves can "export" to the rest of the protein in the form of plant amino acids.
