下图表示动物、植物细胞二合一显微结构模式图。根据图回答(符号与文字全对才给分)：

(1)若某细胞同时含有AB两图中各种细胞结构，则为      细胞；
(2)提供细胞能量的“动力车间”为[    ]        ；                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
(3)结构5为                 ，在植物细胞有丝分裂时，与细胞壁的形成有关；
(4)细胞内有双层膜的结构但又不属于细胞器
的是              ；
(5)如果B图为大蒜根细胞，则应该没有[    ]     ； 
(6)与动物细胞有丝分裂有关的结构是[    ]              ；
(7)12所示的结构的化学组成为       和        ，它与染色体的关系为         。
