Einzelbilder, aufgenommen mit einem 40x0.8 Objektiv. English: Microscopic images of a leaf of the moss Plagiomnium undulatum. Top: brightfield image. Bottom: autofluorescence of the chloroplasts. Single images, recorded with a 40x0.8 objective.
context_page_description: Chlorophyll fluorescence is light re-emitted by chlorophyll molecules during return from excited to non-excited states. It is used as an indicator of photosynthetic energy conversion in higher plants, algae and bacteria. Excited chlorophyll dissipates the absorbed light energy by driving photosynthesis, as heat in non-photochemical quenching or by emission as fluorescence radiation. As these processes are complementary processes, the analysis of chlorophyll fluorescence is an important tool in plant research with a wide spectrum of applications.
