【Abstract】 After treated by toxin,the higher concentration and the more prolong of time,the more serious the phasmolysh was,and the disruption of membrane cell;the swollen of chloroplast,the disappearing of membrane,the disordering of chloroplast lamellae;the damage on membrane and ridges of mitochondria;the damage on membrane of nuclei.
