My name is woof. You think that we have a great life，right？Wrong！I am going to tell you why.

First of all，we are bored. Bored. bored. And bored. Do you ever think about what a dog does all day？ Nothing. Nothing at all. Our owners are busy，you know，working，going to school，away from home all day. So what are we supposed to do？Watch the house or apartment？Sure. That is like watching paint dry or grass grow. Boring. That’s why we get so excited when our owners come home. We bark and run around and act as if we are very happy. But we only do this because we are bored all day. If we are lucky，our owner take us for a walk.

Then there is the food. We eat the same food，meal after meal，day after day，week after week，month after month. Help！Would you like  to eat the same thing all the time？No，you would not. So what makes you think we dogs like it？We don’t. We hate it.

Another thing-television. Another thing-television. Dogs hate television. Our owners watch these stupid programs，hour after hour，night after night. Are there any programs for dogs on television？No. Not a single one.

So what can we do？What else can we do but sleep？And so we sleep. We dogs are not lazy，we are bored.

填空题 案例分析题

现有甲、乙两个烟草品种（2n＝48），其基因型分别为aaBB和AAbb，这两对基因位于非同源染色体上，且在光照强度大于800勒克司时，都不能生长，这是由于它们中的一对隐性纯合基因（aa或bb）作用的结果。取甲乙两品种的花粉分别培养成植株，将它们的叶肉细胞制成原生质体，并将两者相混，使之融合，诱导产生细胞团。然后，放到大于800勒克司光照下培养，结果有的细胞团不分化，有的能分化发育成植株。请回答下列问题：

将叶肉细胞制成原生质体时，使用（）破除细胞壁。
