光合作用是绿色植物所特有的生理过程,是物质生产的主要途径。在光合作用过程中,植物利用自身的叶绿素来吸收太阳投射到叶面的辐射能,引起 H_2O 的光解,并利用水光解放出的 H(H~+和电子)将 CO_2还原成有机物,从而把太阳辐射能转化为贮藏在有机物中的化学能。光合作用与人类关系非常密切,每天进食的粮食、蔬菜和水果,都是光合作用产物,用的木材、棉花、纤维等工业原料,也是光合作用产品;甚至于被人类利用的煤炭、石油、天然气等,也是亿万年前的植物通过光合作用蓄积起来的太阳能。
Photosynthesis is a green plant-specific physiological processes, is the main way of material production. During photosynthesis, plants use their own chlorophyll to absorb the radiation energy projected by the sun onto the foliage, causing photolysis of H 2 O and reducing the CO 2 to organic matter using H (H + and / or E Convert solar radiation into chemical energy stored in organic matter. Photosynthesis and human beings are very closely related to the daily consumption of food, vegetables and fruits are photosynthesis products, wood, cotton, fiber and other industrial raw materials, but also photosynthetic products; and even by human use of coal, oil, natural gas And so on, but also hundreds of millions of years ago by photosynthesis plant accumulation of solar energy.
