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 H …

Jan 11, 2016 · It wasn’t until 20 years later, from 1862-64, Julius von Sachs investigated how starch is produced under the influence of light and in relation to chlorophyll. Reactions Photosynthesis has two main sets of reactions. Light-dependent reactions need light to work; and light-independent reactions, which do not need light to work.
Julius von Sachs found starch to be the first visible product of photosynthesis and emphasised the role of light, carbon dioxide and chlorophyll in the synthesis of starch. The action spectrum of photosynthesis was first performed by T. W. Engelmann (1882) who found that photosynthesis is most efficient in red and blue-violet light.

In particular, they developed a method for growing plants directly in a solution containing mineral elements: hydroponics. von Sachs also demonstrated that the starch grains present in chloroplasts are formed under the influence of light (see Some Pioneers of Photosynthesis ).
In 1854, Julius Von Sachs proved that glucose is produced during the process of photosynthesis in the green parts of the plant. He also found that starch is the storage form of glucose in plants. Furthermore, he showed that chloroplast is the cell organelle that houses the green pigment chlorophyll in plants. Suggest Corrections 0 Similar questions
Julius von Sachs B Cornelius van Niel C T.W . Engelmann D Jan Ingenhousz Solution: • He split light into its spectral components (VIBGYOR) by using a prism and then illuminated a green alga (Cladophora) placed in the suspension of aerobic bacteria. The bacteria were used to detect the sites of O2 evolution.
Julius von Sachs was the first scientist to provide evidence of the production of glucose when a plant grows. He also told the world that the light-absorbing pigments of photosynthesis are located in chloroplasts. In 1770, Joseph Priestley did experiments to claim that air plays a crucial role in the growth of a plant.
