Photosynthetic Action Spectra of Marine Algae
A polarographic oxygen determination, with tissue in direct contact with a stationary platinum electrode, has been used to measure the photosynthetic response of marine algae. These were exposed to monochromatic light, of equal energy, at some 35 points through the visible spectrum (derived from a monochromator). Ulva and Monostroma (green algae) show action spectra which correspond very closel...
متن کاملRelationship between action spectra for chlorophyll a fluorescence and photosynthetic O2 evolution in algae
Relative excitation spectra of chlorophyll a fluorescence are shown to be very close to relative action spectra of photosystem II O2 evolution in seven microand macro-algae of five phyla. The conditions under which this correspondence should hold, based on theoretical considerations, and the applications of this correspondence to interpretation of fluorescence excitation spectra of chlorophyll ...

متن کاملThe Effects of Marine Algae on Osteoporosis
Background: Osteoporosis is a prevalent bone disease caused by an imbalance between bone formation and resorption. Nutritional factors are involved in the prevention of osteoporosis. Several treatments exist for osteoporosis including bisphosphonates, parathyroid hormone, estrogen therapy, and hormone therapy, which have their own side effects. In the quest for an appropriate treatment for os...
متن کاملPhotosynthetic action spectra of trees: I. Comparative photosynthetic action spectra of one deciduous and four coniferous tree species as related to photorespiration and pigment complements.
Comparative isoenergetic action spectra of net photosynthesis for intact, current year foliage of five tree species were determined from 400 to 710 nm by CO(2) exchange analysis. The blue (400 to 500 nm) peak of net photosynthetic activity for the green broadleaves of red alder (Alnus rubra Bong.) was reduced to a plateau for the green needle-leaves of Douglas-fir (Pseudotsuga menziesii [Mirb.]...
