photosynthesis The process by which plants transform carbon dioxide and water into carbohydrates and other compounds, using energy from the sun captured by chlorophyll in the plant. Oxygen is a by-product of the process. Photosynthesis is the essence of all plant life (autotrophic production) and hence of all animal life (heterotrophic production) on the planet Earth. The rate of photosynthesis depends on climate, intensity and duration of sunlight, available leaf area, soil nutrient availability, temperature, carbon dioxide concentration, and soil moisture regimes (这个过程所产生的二氧化碳和水直接转化成碳水化合物和其它化合物，太阳能驱动光和作用。叶绿素氧是光和作用过程产生的一种副产品。光合作用的本质是一切植物生命(自养生产)的来源，因此地球上所有的动物都是异养生产。光合作用的速率取决于气候、阳关强度和持续时间、叶面积、土壤养分有效性、温度、二氧化碳浓度、土壤水分等因素。) |
