李明同学学习了植物生殖的知识后,想观察一下玉米是怎样结出果实、种子的,于是种了些玉米.当玉米开花时,李明又担心玉米受粉不好,采用了人工授粉.正好他表弟来他家玩,他表弟就帮他忙.但让他气愤的是,表弟帮助授粉的玉米没有结出果实或结出的果实稀稀拉拉,子粒很少.原来表弟在采集花粉时,并没有采集玉米的花粉,而是出于好玩,采集旁边别的植物的花粉.于是他产生了疑问:植物是不是一定要接受同种植物的花粉才能结出果实呢?

(2)实验过程中,他重新种植了一些玉米(不考虑季节影响),并将这些玉米平均分成差不多的甲、乙两组.快开花时,将所有雄花去掉,并分别用半透明纸袋将玉米雌花穗包起来,这样做的意义是______.

(3)分别采集玉米花粉和油菜花粉,将玉米花粉撒到包好的甲组玉米雌花穗上,将油菜花粉撒在乙组玉米雌花穗上.根据假设可以预测,能够形成果实的一组应该是______.要设计另一组的意义是______.
