WebIn Engelmann's classic experiment, why were the oxygen-requiring bacteria clustered around the regions of Spirogyra algae that were bathed in red, blue, and violet light? Photosynthesis is most active in those wavelengths of light and thus more oxygen is produced by the algae in those regions. Webin neither photosynthesis nor respiration Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. Web沈 维,张 林,罗天祥. 中国科学院青藏高原研究所,高寒生态与生物多样性重点实验室, 北京 100101. . 高山林线变化的更新受限机制研究进展 child clinical observations

The Englemann Experiment by Joshua Wolfe - Prezi

Webphotosynthesis. Early action spectra Theodor Engelmann (1843–1909) almost certainly described the first experiments that employed light-induced images of living systems … Engelmann's major contribution to the field of physiology emerged from a study lasting from 1873 to 1897, in which he observed the contractions of striated muscles. Focusing on the visible bands of fibers in the muscles, he noted that the volume of the anisotropic band increased during contraction, whereas the volume of the isotropic band decreased. He theorized that it was this interaction between the two bands which allowed for muscle contraction.

An action spectrum is a graph that illustrates the efficacy of different wavelengths of light in promoting photosynthesis. Engelmann's elegant experiment in Question 4 is an example of an action spectrum where the efficacy of various wavelengths of light was measured by the production of oxygen and the clustering of bacteria.
