Hint: Julius von Sachs demonstrated that plants could be grown in a specified medium without soil and one could use any non-soil medium containing food sources to grow plants.
Complete step by step answer:
Julius von Sachs was a German botanist whose experimental studies of nutrition, tropism, and water transportation improved plant physiology and the cause of experimental biology in general during the second half of the nineteenth century. Sachs began working as an assistant to physiologist Jan Evangelista Purkinje at the University of Prague, earning his Ph.D. in 1856. In 1859, he was named physiology assistant at the Agricultural Academy of Tharandt in Saxony. Two years later, he was appointed director of the Agricultural Academy in Poppelsdorf, near Bonn. In 1867, he assumed the chair of botany at Freiburg-im-Breisgau University. Julius von Sachs demonstrated that plants could be grown in a specified medium without soil leading to maturity. Von Sachs saw that plants would grow in the medium of moss, lichen, and peat without soil.
Additional information Julius von Sachs verified during the starting of 1861, that flowers produced starch via means of the assimilation of Carbon dioxide. He confirmed that the assimilation takes place within the chloroplasts, which incorporate the chlorophyll pigment molecules. He discovered that if a leaf containing starch is stored in darkness for a while, the starch disappears and if the identical leaf is uncovered to sunlight, the starch reappears in chloroplasts.
Note: Julius von found that the plants would grow on a clay substrate and called it a pot culture. This discovery was published in 'Irrigation and Plant Nutrition as "Wasserlosungen." It was also translated into English and published in two parts: "Nutritional Studies with Pot Cultures'' (1934) and "Irrigation Studies with Pot Cultures" (1936).
