B、 To stimulate the walls of a particular cell to produce other oligosaccharins
C、 To activate enzymes that release specific chemical messengers from plant cell walls
D、 To duplicate the gene complement in a particular plant cell
E、 To produce multiple effects on a particular subsystem of plant cells
答案:
A
提问：
请问张慧雯老师，这题限时做题时定位直接到最后一段，因为只有最后一段是在直接讲oligosaccharin，所以直接选到C这个迷惑选项。虽然有关注到activate这个动作好像不是oligosaccharin发出的，但是其他选项都不像，限时下就直接选了，请问这里如何思考呢？
