The photosynthetic apparatus of algae and plants are very similar because both of them contain the two phótosynthetic reaction centers of PSⅡ and PSⅠ and have the same photosynthetic function. Therefore, study of the photosynthesis of algae has a common significance. On the other hand, the light-harvesting antennae of plants are chlorophyll a/b-protein complex in thylakoids while those of algae are the phycobilisomes. A phycobilisome is a large super-展开更多

The ex-perimental results indicated that the energy transfer from PBS to two reaction centers of PS Ⅰand PS Ⅱ were parallel, and confirmed the model which was suggested by Mullineaxu.展开更多
