During the process of photosynthesis, green plants prepare their food. A green pigment, chlorophyll converts raw material into carbohydrates in the presence of solar energy. From the given options, Julius von Sachs proved that chlorophyll was present in special bodies named chloroplasts.
Apr 29, 2015 · Julius von Sachs made other major discoveries besides the existence of florigen. For example, he discovered chloroplasts and the fact that they produce sugar. He also discovered that glucose is stored in the form of starch in granules. In other words, the mystery of florigen was as old as much of the fundamental knowledge in plant biology.
Julius von Sachs demonstrated in the beginning of 1861, that plants produced starch by the assimilation of Carbon dioxide. He showed that the assimilation occurs in the chloroplasts, which contain the chlorophyll pigment molecules. He observed that if a leaf containg starch is kept in darkness for a while, the starch disappears and if the same ...
11-14. 14-16. post-16. This video clip from Botany: A Blooming History demonstrates the classic experiment to show that light is needed for the production of starch, placing it in the context of pioneering 19th century scientist Julius von Sachs. Julius von Sachs became Head of the botanical institute at Würzburg University in 1868.
The first recorded realization that plants need sustenance to survive, like animals, came from Aristotle around 350 B.C.E, however it was Aristotle's student, Theophrastus, who made a greater contribution to the discovery of photosynthesis. Theophrastus is considered the "father of botany" because of his work with categorizing plants, but also ...

The empirical equation representing the total process of photosynthesis for oxygen evolving organisms was then understood as: where [CH2O] represented a carbohydrate (e.g., glucose, a six-carbon sugar). A milestone contribution to the understanding of photosynthesis was that made by a microbiologist, Cornelius van Niel (1897-1985), who, based ...
