Successful microscopy depends at least on three parameters: the quality of the microscope, the qualification of the experimenter, and the quality of sample preparation. Concerning the quality of microscopes, Jena was the distinguished site for optical instruments made for microscopic investigations because this was the home of ZEISS and the domain ...
For investigations related to karyokinesis, he used mainly two species: Tradescantia virginiana (Dicotyledonae) and Fritillaria imperialis (Monocotyledonae). From the former, he prepared stamen hairs (Fig. 3); from the latter, the first layer of developing endosperm from embryo sacs. By a comparison of different stages of nuclear divisions, he was ...
Cell division, i.e., cytokinesis, in its various forms is one of Strasburger’s major research topics. His study objects ranged from algae to flowering plants, e.g., Spirogyra orthospira, Phaseolus multiflorus, T. virginiana, and many others. For Spirogyra, he describes in extenso the process of cell division (Fig. 4) by a ring-like, protoplasma-ric...
Strasburger was extremely fascinated by the dynamic behavior of the protoplasm. For the century to come, his observations of cytoplasmic streaming in different algae like Spirogyra and Nitella; staminal hairs of flowering plants such as T. virginiana, Momordica elaterium, and some Lamiaceae; root hairs of Hydrocharis morsus-ranae; and mesophyll cel...
In 2005, Elizabeth Lord, an established expert in the field, wrote: “the biology of the in vivo pollen tube cell remains somewhat of a mystery though, due to the technical difficulties encountered in observing pollen tubes in the style” (Lord 2005). So much more are Strasburger’s investigations to be admired. He observed the growth of pollen tubes,...

Apr 15, 2012 · Eduard Strasburger was one of the most prominent biologists contributing to the development of the Cell Theory during the nineteenth century. His major contribution related to the characterization of mitosis and cytokinesis and especially to the discovery of the discrete stages of mitosis, which he termed prophase, metaphase and anaphase.

Eduard Strasburger, director of the Botany Institute and the Botanical Garden at the University of Bonn from 1881 to 1912, was one of the most admirable scientists in the field of plant biology, not just as the founder of modern plant cell biology but in addition as an excellent teacher who strongly believed in “education through science.

Eduard Adolf Strasburger. 1844-1912. German plant cytologist who studied nuclear division in plants. Strasburger accurately described the embryonic sac in gymnosperms (conifers and others) and angiosperms (flowering plants). He explained the basic principles of mitosis and declared that new nuclei can arise only from the division of other ...

Life and work of Eduard Strasburger (1844-1912) The plant scientist wrote one of the best known textbooks on plant sciences already many decades ago. The book is still being published today. But the findings of Eduard Strasburger once were fiercely dabated and some of them proven more than 60 years after their first publication.
