what did Julius Von Sachs say about chlorophyll
Answers
Julius von Sachs (1832 -1897). He was a German botanist and physiologist. He achieved fame for his authorship of several books which have been translated to English and became standard textbooks in general botany and plant physiology. He initiated experimental plant physiology and may be regarded as the pioneer in the conduct of studies on the physico-chemical aspects of photosynthesis (Nickelsen 2007).
☛Published in 1862, he concluded that “the chlorophyll grains [= the chloroplasts] are the only and sole place where starch is formed from inorganic matter” and “the embedded starch grains in the chlorophyll are not only a secondary phenomenon but are formed under the influence of a certain light intensity by means of the assimilating action of the latter.”
☛Julius von Sachs continued his study and, in 1864, reported that both the production and storage of starch were affected by the exposure of plants to minimum light intensity.
