Within it, photosyntheticreaction-centres collect solar energy to drive the transformation of water and carbon dioxide in the air into sugars that nourish and build the plant.
在它的内部，光合反应中心收集太阳能，驱动水和空气中的二氧化碳形成糖，滋润并造就了我们的星球。

With the research of chlorophyll fluorescence parameters may reflect the energy utilization in photosyntheticreaction center and changes of biological activity when the plants under drought stress.
The photosynthetic rate of detached leaves and Hill reaction of chloroplast were inhibited graviously during chilling treatment, and the electrolyte leakage of leaves was increased by chilling.
