aCarbon dioxide gas- found in nature and used by plants during photosynthesis, is compressed to its ‘critical’ state where it becomes a liquid 植物发现本质上和使用的二氧化碳气体在光合作用期间,被压缩对它的`重要’状态,它成为液体[translate]...
The device Reisner and his colleagues produced is inspired by photosynthesis--- the natural process by which plants use the energy from sunlight to turn carbon dioxide into food. On the artificial leaf,two light absorbers,similar to the molecules in plants that harvest sunlight,are combined with ...

So first, sugar is created through photosynthesis, then it's converted into starch, and it's set for storage, usually in the roots of the tree. Then as springtime approaches, the starch is converted back into sugar. The sugar and starch is dissolved in this watery liquid that we call ...
A homogeneous gas mixture is set up in the cuvette and the gas interacting with the leaf analysed for CO2 and, if required, H2O concn.$ The photoacoustic gas measurement principle in a gas analyser (3) is used. The leaf cuvette and analyser unit can be held in the hand during gas ...
The ratio between variable-to-initial chlorophyll fluorescence (Fv/Fo) and the maximum quantum yield efficiency of the photosystem II (Fv/Fm) was used to explore damage associated with the functioning of the photosynthetic apparatus. A strong, nonlinear correlation between physiological parameters and ...

Low night temperature and high photon flux density during the daytime, which are very common during the growing season in the field, cause a reduction in photosynthesis of the plant. The probable underlying damage during inhibition is likely repairable indicating protection rather than damage. The ...
