Ⅰ 萤火虫为什么会发光
原来它们发光的部分是在腹部最后两节，这两节在白天是灰白色，在黑夜才能睁拆发出光亮。光是通过明凳透明的表皮而发出的，表皮下面是一些能发光的细胞，发光细胞的下面是另一些能反射光线的细胞，可以看到其中充满着小颗粒，称为线粒体。线粒体能把身体里所吸收的养分氧化，合成某种含有能量的物质。发光细胞里含有很多线粒体，说明它们能制造比较多的含有能量的物质。发光细胞还含有两种特别的成分：一种叫做荧光素激早旅，一种叫做荧光酶。荧光素和含能量的物质结合，在有氧气时，受荧光酶的催化作用，使化学能转化为光能，于是产生光亮。萤火虫常常一闪一闪地发光，是因为它能控制对发光细胞的氧气供应的缘故。
萤火虫发光的颜色不同，是由于它们所含的荧光素和荧光酶各不相同。萤火虫的发光有引诱异性和使同类聚集的作用，我们可以看到捉在小玻璃瓶里的萤火虫可引诱在较远处的萤火虫向小瓶飞来。
