The reason is that green plants under sunlight undergo photosynthesis while respiring, hence they consume the carbon dioxide in air and release oxygen in return.

由於绿色植物在阳光下，除了进行呼吸作用外，亦同时进行光合作用，消耗空气中的二氧化碳，同时放出氧气，这便有助保持空气中二氧化碳和氧气含量的相对恒定。

The results shoed that after spraying 1 and 5 mgL^(-1) of anthraquinones, the photosynthetic rate raised by 38.03% and 39.73%, chlorophyll content increased by 3.53% and 3.83%, and MDA content decreased by 11% and 23%, respectively. The anthraquinones could absorb solar UV radiation, and convert the harmful UV into blue or yellow light which can promote plant photosynthesis. It as suggested that foliar-spraying appropriate concentrations of aloe's anthraquinones could promote wheat photosynthetic activity, alleviate UV harm, and thus, increase wheat yield.

结果表明：在灌浆期用浓度为1和5mgL^(-1)的芦荟蒽醌类物质喷施小麦，光合作用速率分别提高了38.03%和39.73%；叶绿素含量分别提高了3.53%和3.83%，丙二醛含量分别降低了11%和23%；蒽醌类物质能够吸收太阳中的紫外线，并将紫外线转换成能促进光合作用的蓝光或黄光；芦荟蒽醌类物质能促进小麦光合作用效率，减轻紫外线对小麦的损伤；喷施合适浓度的芦荟蒽醌类物质能够提高小麦产量。

The most important part of this building process, which is called photosynthesis, is the production of carbohydrates such as sugars, starches and cellulose.

这项建设过程中最重要的组成部分，被称为光合作用，是碳水化合物，如糖，淀粉和生产纤维素。

The result of these varieties is to accelerate photosynthesis and improve seedlings bio-mass accumulation.There exists some remarkable plus correlative relation between Machurian Ash seedling leaf net photosynthetic rate under light saturated condition and leaf nitrogen content.

水曲柳幼苗叶片的光饱和净光合速率与叶片氮含量之间也存在着强烈的正相关关系，适当提高氮素养分的供应会相应增加叶片中的氮含量，从而促进植物光合作用，有利于生物量的积累。

Based on the field experiments, the daily variations of photosynthesis rate and transpiration rate and water use efficiency were compared on the condition of sprinkle irrigation and border flooding irrigation.

通过定点定位试验，比较了喷灌与常规畦灌条件下农田生态环境、冬小麦光合速率和蒸腾速率的日变化特征以及不同水平的水分利用效率。

To elucidate the biological structure basis of transgenic rice plants expressing maize PEPC gene with high photosynthesis efficiency, PEPC transgenic rice and its wild type with at 3 leaves seedling stage were treated under 1000 μmol/(m^2s) light intensity for 100 min, respectively, and those under 200 μmol/(m^2s) light as the control. The structure of mesophyll cells, bundle sheath and thylakoids of the second blade were observed with a transmission electron microscope.
