From theCambridge English Corpus It is the signature from land surfaces that will yield the most detectable evidence forphotosynthesis. From theCambridge English Corpus Either the purple bacteria have acquired thephotosynthesisgenes recently by lateral gene transfer or selective pressure forced various species to retain these organizational patterns. From theCambridge English Corpus These hypotheses will be tested as additional genomic, biochemical and geological evidence sheds more light on the evolution of nitrogen fixation,photosynthesisand cyanobacteria. From theCambridge English Corpus Evidence presented above decreases the likelihood that alterations in canopy processes such asphotosynthesisand transpiration are responsible for these changes at the forest edge. From theCambridge English Corpus Leaf structure (specific leaf area) modulatesphotosynthesis-nitrogen relations: evidence from within and across species and functional groups. From theCambridge English Corpus The leaves were not only used forphotosynthesismeasurement but also for repeated monitoring of herbivory rate. From theCambridge English Corpus After these immediate measurements, samples were then placed on ice and tested for activephotosynthesisat various time intervals afterward. From theCambridge English Corpus Therefore, maximizing the proportion of leaves within the canopy will increase overallphotosynthesis. From theCambridge English Corpus Photosynthesiscould have continued beneath this bare ice if it was thin and clear. From theCambridge English Corpus It is difficult to determine whether the results reflect the history ofphotosynthesis. From theCambridge English Corpus This then allowsphotosynthesisto operate effectively over a wide range of incident light-intensities. From theCambridge English Corpus Understandingphotosynthesisis important for understanding life, the development of the atmosphere on earth and possibly renewable hydrogen generation in the future. From theCambridge English Corpus Netphotosynthesiswas higher in the grafted plants throughout the whole period. From theCambridge English Corpus Photosynthetic induction strongly affects the light compensation point of netphotosynthesisand coincidentally the apparent quantum yield.
