Sachs, Julius Von 1832-1897. Julius Sachs, the outstanding German botanist and plant physiologist, was born in Breslau in 1837. He left school in 1851 and became assistant to the physiologist J.E. Purkinje at Prague. In 1856 he received the degree of Doctor of Philosophy and established himself as Privatdozent for plant physiology in the same ...
It was finally in 1930 that Cornelis Bernardus van Niel (1897-1985), a Dutch-American microbiologist (Figure 8), demonstrated that photosynthesis is a light-dependent redox reaction, in which the hydrogen of an oxidizable compound (H 2 A) reduces carbon dioxide to cellular material (CH 2 O)x. This reaction is expressed according to the equation ...
Jan 29, 2024 · It is the site of photosynthesis, a process where light energy is converted into chemical energy, fueling the organism’s activities. Discovery and Word Origin. The discovery of chloroplasts dates back to the 19th century, with early microscopic observations made by botanists such as Julius von Sachs.
Solution. 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.
Later, Julius von Sachs discovered that plants were capable of producing glucose. T.W. Engelmann established the role of chlorophylls in plants, and Cornelius van Niel found that plants release oxygen from water (H2O), not carbon dioxide, during the photosynthesis process. He also provided the equation for photosynthesis in general.
