3 days ago · Julius von Sachs was a German botanist whose experimental study of nutrition, tropism, and transpiration of water greatly advanced the knowledge of plant physiology, and the cause of experimental biology in general, during the second half of the 19th century.

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 ...
Then there is his resuscitation of the method of "water-culture," and the application of it to the investigation of the problems of nutrition. Most important are his experiments, developing the concept of photosynthesis, that the starch -grains, found in leaf chloroplasts, depend on sunlight.
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.
Dec 13, 2019 · We highlight here the important role of modelling in deciphering and untangling complex photosynthesis processes taking place simultaneously, as well as in predicting possible ways to obtain higher biomass and productivity in plants, algae and cyanobacteria.

May 17, 2018 · The year 2018 marks the 150th anniversary of the first publication of Julius von Sachs' (1832–1897) Lehrbuch der Botanik ( Textbook of Botany ), which provided a comprehensive summary of what was then known about the plant sciences. Three years earlier, in 1865, Sachs produced the equally impressive Handbuch der Experimental-Physiologie der ...
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.
