Jan 10, 2022 · Reviewed by Govindjee and Krogmann (2004), Sachs showed that starch grains are produced in plant leaves and that these are the first visible product of the process of photosynthesis. He also takes credit for proving that the green pigment chlorophyll in the chloroplast is involved in photosynthesis. In her 2007 paper From Leaves to Molecules ...
5 days ago · In 1862 and 1864 he proved that the starch present in the chloroplasts results from the absorption of carbon dioxide, and he established that starch is the first visible product of photosynthesis.

Dec 13, 2019 · The role of CO 2 in photosynthesis was shown by Jean Senebier (1782), whereas the synthesis of starch was shown by Julius von Sachs (1862, 1864). However, the involvement of chlorophyll (Chl) in this process has a long history.

Using an elegant experimental approach involving iodine to treat leaves from con-specifics grown in sunlight and in the dark, Sachs (1865) proved his concept of how plants use sunlight to manufacture their living substance.
May 17, 2018 · Julius Sachs (1832–1897), who has been quite rightly called “the father of plant physiology,” was a German physiologist of international standing, whose research interests contributed to ...
Most important are his experiments, developing the concept of photosynthesis, that the starch -grains, found in leaf chloroplasts, depend on sunlight.
3. Appearance of starch grains in plants are the first visible product of photosynthesis. 4. Suggestion that substances other than carbohydrates such as growth regulating substances may regulate flowering in plants. Sachs was one of the greatest teachers of the 19th Century and had a great influence on British and American botany and horticulture.
