The Subcellular Origin of Bioluminescence in Noctiluca miliaris
The light emitted by Noctiluca has its origin in 1 to 5 x 10(4) organelles ("microsources") which are scattered throughout the perivacuolar cytoplasm, and which appear to be the elementary functional units of bioluminescence. Microscopical techniques, image intensification, and microphotometry were employed in their investigation. Microsources are fluorescent, strongly phase-retarding, and rang...
متن کاملShort Communication Distribution of Ion Channels in the Membrane of the Dinoflagellate Noctiluca Miliaris
Noctiluca miliaris, a marine dinoflagellate, exhibits spontaneous flexion of its tentacle. The movement of the tentacle is always accompanied by perturbations of membrane potential, termed the 'tentacle regulating potentials' (TRPs) (Eckert and Sibaoka, 1967). Though the waveform of the TRPs is liable to variation, it consists of four successive basic components: (1) a Na-dependent depolarizing...
متن کاملCorrelation between membrane potential responses and tentacle movement in the dinoflagellate Noctiluca miliaris.
Membrane potential responses and tentacle movement of the marine dinoflagellate Noctiluca miliaris were recorded simultaneously and their time relationships were examined. The food-gathering tentacle of Noctiluca exhibited slow extension-flexion movements in association with the spontaneously recurring membrane potential responses termed the tentacle regulating potentials (TRPs). The flexion of...
متن کاملHippokrates Ueber die Krankheiten III
irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...
