   Did Dutrochet have a nucleus?

   • Nuclei were discovered as conspicuous features of the "cell." So that when Schwann pro- duced his treatise it was on the basis of a wealth of knowledge that Dutrochet had not possessed. Even in the x837 edition of his work there is no evidence that Dutrochet had done any significant investiga- tion on the subject since the original edition of I824.

   Who invented cellular theory?

   • Chromosomes, globules The cellular theory was produced in two steps by Schleiden and Schwann (1838–1839) and then by Remak (1855) and Wirchow (1855–1858). This theory claimed that cells were universal and microscopic entities, constituting living beings and that a cell was always produced by the division of another cell.

   What did Dutrochet discover about plant physiology?

   • In the area of plant physiology, Dutrochet recognized the significance of green pigment in the use of carbon dioxide, investigated the mechanisms of respiration, light sensitivity, and geotropism, and showed that internal plant transport involves osmosis. He demonstrated that mushrooms are the reproductive bodies of the mycelium.

   Dutrochet is also considered to be the founder of the cell theory; but his ideas are actually more in the nature of shrewd, intuitive anticipations rather than conclusions based on his own microscopic observations. His illustrations are not convincing and it seems that, at least in some cases, Dutrochet’s “globules” (cells) were optical ...

   A few years later, René Joachim Henri Dutrochet (1776–1847), who had discovered the osmotic phenomenon, claimed that cells constituted plants. However, in the wall of these cells there could be some little globules that could be the fundamental entities.
